Pls answer the McQ cactus questions Question 1: COMPREHENSION Read the following unedited passage and pick the statement(s) that is/are accurate among the options provided. In China, domestic sewage discharged from decentralized villages is important component of non-point source (NPS) pollution, and causing severe degradation of aquatic ecosystems and rural environments. Constructed wetland (CW) is regarded as an attractive alternative for decentralized wastewater treatment and NPS pollution control because of its low cost and high convenience to construct and operate Other benefits such as eco-friendliness, high sustainability and aesthetic value also make CW a popular wastewater treatment technology. Pollutants are removed by integrated physical, chemical and biological processes in CW, including plant uptake, substrate adsorption and the most importantly, microbial degradation. Studies have found dissolved oxygen (DO) concentration to be key parameter affecting microbial processes for pollutant removal in CWs. In horizontal subsurface-low constructed wetlands (HSSCWs), a CW type, Anoxic conditions are usually prevailing due to poor reaeration, which favors anaerobic processes such as denitrification. However, aerobic reactions, especially nitrification, tend to be restrained in many HSSCWs, leading to less nitrogen removal efficiency. A. In HSSCWs, anoxic conditions prevail, and nitrogen removal efficiency is lower owing to limited nitrification. B. NPS pollution control has benefits such as eco-friendliness, high sustainability, and aesthetic value, in addition to being inexpensive and easy to construct and operate. C. Microbial degradation is an important step in the operation of CW systems, and dissolved oxygen concentration has been reported to be a key factor in this step. D. Severe degradation of aquatic ecosystems and rural environments can be completely eliminated using CW, which is a popular wastewater treatment technology.

The environment is negatively affected by emissions of conventional internal combustion (IC) engines, since they emit a lot of greenhouse gases and other harmful pollutants. This necessitates the search for alternative fuels with low carbon emissions for IC engines [1–2]. Hydrogen, a clean and renewable resource, is considered a promising candidate by many researchers [3–5]. Automobile manufacturers have developed hydrogen-fueled internal combustion engines (HICEs) and tests have shown that HICEs have good power performance and reliability, with almost zero carbon emissions [6–10]. However, NOX is one of the major pollutants emitted by HICEs. HICEs usually generate large amounts of NOX emissions under high loads, which is an inevitable phenomenon and is attributed to the temperature rise in the cylinder [11–14]. Technologies such as lean burn, retarded ignition, and exhaust gas recirculation have been found to be effective in reducing NOX emissions. These studies have investigated the variation in NOX emissions with changes in the control parameters of IC engines, using experimental methods. However, the mechanism of NOX formation has not been discussed in sufficient detail. A. Conventional internal combustion (IC) engines emit large quantities of greenhouse gases and other harmful pollutants, which have an adverse impact on the environment. B. In their search for alternative fuels that use less carbon in IC engines, researchers have found that hydrogen can be used to create a fuel that may be considered promising. C. Because of the temperature rise in the cylinder, HICEs generate a lot of NOX emissions under high loads through lean burn, retarded ignition, and exhaust gas recirculation. D. In some previous studies, researchers have focused on how NOX emissions vary with changes in the control parameters of IC engines, using experimental methods, but the mechanism of NOX formation needs to be investigated further.

Test Name : Earth and Environmental Sciences ☰ 1:29:25 Question 4: COMPREHENSION Read the following unedited passage and pick the statement(s) that is/are accurate among the options provided. The permeability, an important hydrogeological parameter, is of interest because it largely governs the generation of high pore pressure and the transport of flow and heat in the groundwater system. A lot of laboratorial experiments and field observations show that earthquake-generated seismic waves can increase permeability. Based on these researches, some mechanisms were proposed: fracture unclogging, fracture aperture alteration with fluid pressure, and new fracture creation. However, there are still some open questions about the permeability change. One question arises from some studies finding that earthquakes can decrease permeability in groundwater aquifers, but this has not been fully studied. A series of earthquakes were shocked the New Zealand since 2010 to nowadays on the Greendale Fault. In this paper, we revisited to the main earthquake in the series, Mw 7.1 Darfield earthquake which happened on 4 September 2010, and analysis how its affected on the groundwater level in the Canterbury Plain. A. Permeability is an important hydrogeological parameter because it is used to generate high pore pressure in groundwater systems. B. Laboratory experiments and field observations used earthquake-generated seismic waves to increase permeability, thereby proposing mechanisms such as fracture unclogging, fracture aperture alteration with fluid pressure, and new fracture creation. C. In contrast to previous findings, some studies reported that earthquakes can decrease permeability in groundwater aquifers. D. The study investigated the Mw 7.1 Darfield earthquake, which occurred on the Greendale Fault in New Zealand, and analyzed its effect on the groundwater level in the Canterbury Plain.

Test Name : Earth and Environmental Sciences ☰ 1:29:15 Question 5: COMPREHENSION Read the following unedited passage and pick the statement(s) that is/are accurate among the options provided. Vegetation phenology is able to directly reflects the growth cycle of plants and its effects on ecosystem productivity, climate, the carbon balance, and human health. Precipitation, insolation, latitude and longitude, topography, and temperature, etc., have an influence on vegetation phenology, of which temperature is the most directly important factor while also serving as indicator of climate change. Many studies have used remote sensing data to explore the relationship between vegetation phenology, climate change, and urbanization. Such studies have shown that urban areas have an earlier start of growing season (SOS) but a later end of growing season (EOS) compared with rural areas, which has generally been attributed to the urban heat island (UHI) effect’s influence on vegetation phenology along the urban–rural gradient (URG). Furthermore, vegetation phenology has a significant correlation with land surface temperatures (LSTs). For example, Zhou used data from 32 major Chinese cities to show that SOS came 9–11 days earlier and EOS 6–10 days later when LSTs increased by 1 °C. Urban scale is also correlated with vegetation phenology; Li reviewed 4,500 urban areas of various sizes in the United States and showed that SOS came 1.3 days earlier and EOS 2.4 days later when the urban area expanded by a factor of 10. A. Studies using remote sensing data to explore the relationship between vegetation phenology, climate change, and urbanization have postulated that the UHI effect has an influence on vegetation phenology along the URG. B. Vegetation phenology directly reflects the growth cycle of plants and affects ecosystem productivity, climate, the carbon balance, and human health. C. Vegetation phenology is influenced by factors such as precipitation, insolation, latitude and longitude, topography, and temperature, all of which function as indicators of climate change. D. Researchers, using SOS and EOS as metrics, have found that vegetation phenology is correlated with land surface temperature and urban area.

Test Name : Earth and Environmental Sciences ☰ 1:28:55 Question 7: COMPREHENSION Read the following unedited passage and pick the statement(s) that is/are accurate among the options provided. Heavy metal pollutants in great quantities are release into coastal areas, e.g., waste from industrial, agricultural, and residential activities. Such pollutants can be a lot harmful to marine ecosystems and human health due to their persistence, toxicity, bioaccumulation, and non-biodegradability. As a result of the stability of heavy metal pollutants, most such pollutants can be transfer from water to suspended matter and sediment in short duration, which makes unknown but persistent risk. The complex hydrodynamic and physical properties of coastal areas make heavy metals in the sediments able to re-released into the water and then into the marine organisms. These are then bio-accumulated and bio-magnified, and finally enter the human body through consumption or contact with seafood, where they can form metal complexes and chelates that are harmful to the human health. A. Large amounts of heavy metal pollutants are discharged into coastal areas as a result of human activity, and these can be extremely harmful to marine ecosystems and human health. B. Most heavy metal pollutants can be quickly transferred from water to suspended matter and sediment, and these pollutants may be re-released into water and absorbed by marine organisms. C. As marine ecosystems are characterized by persistence, toxicity, bioaccumulation, and non-biodegradability, heavy metal pollutants are extremely harmful to these ecosystems. D. The marine organisms are bio-accumulated and bio-magnified, which results in metal complexes and chelates being formed that directly endanger human health.

Test Name : Earth and Environmental Sciences ☰ 1:28:47 EMMANUEL ODJENIMAH Question 8: COMPREHENSION Read the following unedited passage and pick the statement(s) that is/are accurate among the options provided. Natural water environments are threatened by several harmful chemicals derived from artificial products [1]. Many of these chemicals are endocrine disrupting chemicals (EDCs), which pose a threat to the environment and human health (e.g., causing reproductive and sexual abnormalities) [2]. Bisphenol A (BPA), a representative EDC, is highly soluble in water (120 to 300 mg/L), and it is found in drinking, surface, and wastewaters because it is not completely removed during conventional wastewater treatment [5]. Several methods, including physical separations ([6], [7]), biological methods ([1], [5]), and advanced oxidation processes (AOPs) ([2], [8], [9]), have been developed to remove BPA from aqueous solutions. Separation methods, such as adsorption and filtration, are not suitable for low concentrations of BPA when considering the removal efficiency and cost. Additionally, detachment and reprocessing treatments for BPA are required after separation from solution [10]. BPA is readily degraded by microorganisms [11]; however, when using biological methods, the treatment time typically increases linearly with the concentration of BPA. A. EDCs, which are a type of BPA, are known to result in reproductive and sexual abnormalities. B. Conventional wastewater treatment is found to be ineffective at completely removing BPA, as it does not dissolve very well in water. C. Owing to the removal efficiency and cost, physical separation methods such as adsorption and filtration have been found to be unsuitable for removing low concentrations of BPA from aqueous solutions. D. Biological methods can be used to remove BPAs from aqueous solutions, but a limitation of this method is that the treatment time is generally directly proportional to the concentration of BPA.

Test Name : Earth and Environmental Sciences ☰ 1:28:29 Question 10: COMPREHENSION Read the following unedited passage and pick the incorrect statement(s) among the options provided. Damage caused by debris flows occurs during the transportation of material and in deposition zones. Study on the material properties and their relationship with the debris flow characteristics is lacking. In the previous studies, researchers have attempted to identify the relationship between the engineering properties of material and debris flow traits. If a debris flow has a larger mean particle diameter, more coarse grains are contained in a debris flow, and the flow has higher kinetic energy. If the plasticity index of the soil is low, which is occur when the difference between the plastic limit and liquid limit is small, the soil may quickly change from semi solid to liquid state. This may cause huge decrease in the cohesion and angle of internal friction which can lead to slope instability. Other studies have identified that the increase in soil moisture content may contribute to debris flow occurrence by the development of pore pressure in the soil. A. There have been some attempts to determine how material properties affect debris flow traits, but none to determine how they affect debris flow characteristics. B. The mean particle diameter of debris flow depends on the kinetic energy of the flow, and such flow has a higher proportion of coarse grains. C. A lower plasticity index corresponds to a smaller difference between the plastic limit and liquid limit, and soil with low plasticity index may pass from the semi-solid to the liquid state rapidly. D. In some previous studies, researchers have used the development of pore pressure in the soil to identify that increase in the moisture content of soil results in debris flows.
