About this paper
A Sir Adnan one-liner booklet headed '1000- PMS 2026 GK / ONE-LINER (Origionally PMS SCREENING Syllabus BREAKDOWN)' from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack (74 pp). This file publishes Q501-550 only, in the standard MCQ format with verified answers and explanations: 39 published, 11 dropped as internal duplicates of items already published from the same booklet (Q505 = Q43 in the Q1-50 file, wind-to-electricity fact; Q507 = Q45 in the Q1-50 file, verbatim; Q508 = Q188 in the Q151-200 file, geothermal fact; Q510 = Q470 in the Q451-500 file, verbatim; Q512 = Q456 in the Q451-500 file, ozone-UV fact; Q521 = Q442 in the Q401-450 file, verbatim stem; Q524/Q525/Q526 = Q481/Q483/Q482 in the Q451-500 file, SDG 6/7/13 facts reworded; Q530 = Q184 in the Q151-200 file, verbatim, as with the Q472 drop in run 127; Q548 = Q447 in the Q401-450 file, sustainable-water fact), 0 corrections, 1 note flag (Q550 net-zero as balance, not literal zero). No other item in Q501-550 repeats an item already published from the same booklet (checked stem by stem at >=0.8 token similarity against all earlier 1000-booklet files, plus manual fact review). Q551-1000 remain for later runs; the booklet PDF stays in work/pms-screening/.

39 solved MCQs shown directly below
Correct Answer: Greenhouse gas emissions
Climate change is primarily caused by greenhouse gas emissions, which trap heat in the atmosphere.
Correct Answer: Solar, wind, hydro, biomass, geothermal
Renewable energy includes solar, wind, hydro, biomass and geothermal energy, all replenished naturally.
Correct Answer: Coal, petroleum, natural gas, nuclear
Non-renewable energy includes coal, petroleum, natural gas and nuclear fuel, which are finite and deplete with use.
Correct Answer: Flowing water
Hydroelectric power is generated from flowing water, which turns turbines in a dam or run-of-river plant.
Correct Answer: Sunlight into electricity
Solar panels convert sunlight into electricity, using photovoltaic cells.
Correct Answer: Global warming & air pollution
Fossil fuels contribute to global warming and air pollution, through CO2 and pollutant emissions when burned.
Correct Answer: Increased resource use & pollution
Overpopulation affects the environment by increased resource use and pollution, as more people consume more and produce more waste.
Correct Answer: Carbon emissions
Green energy reduces carbon emissions, by replacing fossil-fuel electricity with low-carbon sources.
Correct Answer: Overuse, drought & pollution
Water scarcity occurs due to overuse, drought and pollution, which together shrink usable freshwater supplies.
Correct Answer: Convert seawater to drinking water
Desalination is used to convert seawater to drinking water, by removing dissolved salts.
Correct Answer: Sustainable water use
Water recycling helps in sustainable water use, by treating and reusing wastewater instead of drawing fresh supplies.
Correct Answer: Underground water reservoirs
Aquifers are underground water reservoirs: permeable rock or sediment layers saturated with groundwater.
Correct Answer: Reducing rainfall & groundwater
Deforestation affects the water cycle by reducing rainfall and groundwater, since fewer trees mean less transpiration and recharge.
Correct Answer: Crop rotation & soil conservation
Sustainable agriculture includes crop rotation and soil conservation, keeping soil fertile over the long term.
Correct Answer: Synthetic fertilizers & pesticides
Organic farming avoids synthetic fertilizers and pesticides, relying on natural inputs instead.
Correct Answer: Reducing greenhouse gas emissions
The Kyoto Protocol focuses on reducing greenhouse gas emissions, setting binding targets for developed countries.
Correct Answer: Emission reduction by tradeable permits
Carbon credits promote emission reduction by tradeable permits: emitters can buy credits from those who cut emissions.
Correct Answer: Pollution & overuse
The global water crisis is worsened by pollution and overuse, which degrade and deplete freshwater supplies.
Correct Answer: Increased CO2
Acidification of oceans is caused by increased CO2: seawater absorbs carbon dioxide, forming carbonic acid and lowering pH.
Correct Answer: Rising sea temperatures
Coral bleaching occurs due to rising sea temperatures, when heat-stressed corals expel their symbiotic algae.
Correct Answer: Using less energy for same output
Energy efficiency means using less energy for the same output, through better appliances, insulation and processes.
Correct Answer: Smoke, cooking fuel & dust
Indoor air pollution is caused by smoke, cooking fuel and dust, especially from solid-fuel stoves in poorly ventilated rooms.
Correct Answer: CO, NOx, SO2, particulate matter
Industrial air pollution includes carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2) and particulate matter.
Correct Answer: Ice melting & sea level rise
Global warming leads to ice melting and sea level rise, as glaciers and ice sheets melt and ocean water expands.
Correct Answer: Land productivity & vegetation
Desertification reduces land productivity and vegetation, as degraded dry land supports fewer plants and crops.
Correct Answer: Carbon sequestration & biodiversity
Afforestation helps in carbon sequestration and biodiversity, as new forests store carbon and create habitats.
Correct Answer: Coastal erosion & storms
Mangroves protect against coastal erosion and storms, buffering shorelines against waves and storm surges.
Correct Answer: Energy & resources
Recycling aluminum saves energy and resources: remelting scrap uses far less energy than refining new bauxite ore.
Correct Answer: Pollution & congestion
Sustainable urban planning reduces pollution and congestion, through compact design, green space and public transport.
Correct Answer: Groundwater recharge
Rainwater harvesting helps in groundwater recharge, by collecting rain and letting it percolate into aquifers.
Correct Answer: Habitat & water purification
Wetlands provide habitat and water purification: they shelter wildlife and filter pollutants from water.
Correct Answer: Organic waste in landfills
Composting reduces organic waste in landfills, diverting it to decomposition that produces useful compost.
Correct Answer: Natural environment
Biodegradable waste decomposes in the natural environment, broken down by microbes into simpler substances.
Correct Answer: Long-term pollution
Non-biodegradable waste causes long-term pollution, since plastics and similar materials persist in the environment.
Correct Answer: Environmental risks of projects
An Environmental Impact Assessment (EIA) evaluates the environmental risks of projects before they are approved.
Correct Answer: Oil spills, plastics & chemicals
Marine pollution includes oil spills, plastics and chemicals, the leading pollutants of oceans and seas.
Correct Answer: Oxygen depletion in water
Eutrophication leads to oxygen depletion in water, as algal blooms die and decompose, consuming dissolved oxygen.
Correct Answer: Responsible consumption & production
SDG 12 focuses on responsible consumption and production: using resources efficiently and cutting waste.
Correct Answer: Net-zero carbon emissions
Carbon neutrality means net-zero carbon emissions: the carbon emitted is balanced by carbon removed or offset.
Source & verification
Built by GK360 from verified bank questions — every answer rechecked before publishing. Where the source printed no options, the answer options were prepared by GK360; the questions and correct answers are the verified originals.
Questions
No. It is part 11 (Q501-550) of a Sir Adnan 1000 one-liner practice booklet prepared for PMS Screening 2026. It is published as paperType 'practice', never as a past paper, and the year 2026 is the booklet's label, not a claimed exam session.
Renewable energy includes solar, wind, hydro, biomass and geothermal energy. Non-renewable energy includes coal, petroleum, natural gas and nuclear fuel.
Ocean acidification is caused by increased CO2 absorbed into seawater. Coral bleaching occurs due to rising sea temperatures stressing corals.
The source prints question + answer only, no options; the options are authored distractors under the 2026-10-28 single-format decision, so optionsSource is 'authored'.
