Q.1	A food distribution company aims to reduce food losses during transportation. They decide to conduct an experiment to assess the impact of transportation conditions on perishable goods' decay rates. They exposed a batch of fruits to varying temperatures and monitored their decay rates. What additional factors should they consider to make the experiment comprehensive and applicable to real-world scenarios?
	a) The presence of pests during transportation.		b) Only temperature fluctuations are relevant in transportation experiments.
	c) The origin of the fruits, not the transportation conditions.		d) Humidity levels, transportation duration, and the type of fruit.

Q.2	You are a technician working at a nuclear power plant. You are tasked with performing routine inspections of the plant's various components. To ensure your understanding, your supervisor provides you with a diagram of the plant layout and asks you to identify the labelled components. Based on the diagram below, identify the main components of a nuclear power plant.
	a) A: Steam generator B: Coolant C: Reactor core D: Turbine E: Electricity generator		b) A: Reactor core B: Coolant C: Turbine D: Electricity generator E: Steam generator
	c) A: Coolant B: Reactor core C: Steam generator D: Turbine E: Electricity generator		d) A: Steam generator B: Reactor core C: Coolant D: Electricity generator E: Turbine

Q.3	Scientists have been monitoring the Earth's average temperature for decades. The graph shows the trend they observed. Based on the graph and your understanding of climate change, what is the MOST LIKELY primary cause of the observed rise in Earth's average temperature?
	a) Increased volcanic activity emitting heat-trapping gases into the atmosphere.		b) Excessive use of aerosol sprays releasing harmful chemicals.
	c) Enhanced greenhouse effect due to human activities releasing gases that trap heat.		d) Reduced deforestation leading to a warmer climate.

Q.4	In a disaster-stricken area where access to clean water is limited, a relief organisation assists a local community facing water contamination. The primary water source, a nearby river, has been contaminated by industrial waste, rendering it unsafe for consumption. Boiling water is one known method for purifying it, but the situation requires alternative solutions due to the sheer volume of contaminated water. What additional effective method can be utilised on a larger scale to purify the contaminated water, making it suitable for drinking purposes in such an emergency?
	a) Adding calcium tablets		b) Activated carbon filtration
	c) Pouring it through a coffee filter		d) Employing a reverse osmosis filtration system

Q.5	Consider the case study given below and answer the following question: Case Study: Water Conservation in Singapore Singapore, a water-scarce nation, implemented innovative strategies for water conservation and efficient use. One notable initiative is the "NEWater" program, where wastewater is treated extensively to produce high-grade reclaimed water. This reclaimed water is then used for industrial processes, cooling systems, and even direct consumption after rigorous purification. Additionally, Singapore employs an extensive rainwater harvesting system, collecting rainwater on a large scale for non-potable uses like flushing toilets and watering plants. These initiatives have not only reduced the strain on the city-state's water supply but also ensured sustainable water management for the growing population. As a city planner, how would you promote the adoption of similar water conservation strategies in a different urban area facing water scarcity?
	a) Increase water tariffs to encourage conservation		b) Offer incentives for rainwater harvesting systems
	c) Limit water supply to households to reduce consumption		d) Ignore the issue, as water scarcity is a natural occurrence

Q.6	You're going on a camping trip with your friends, but the nearby stream isn't exactly crystal clear. You're unsure about the type of filter that you should carry with you, so you consider the potential contaminants and location of the stream: Sediment: The stream is a bit muddy after recent rains. Bacteria: You're worried about potential pathogens like E. coli from upstream wildlife. Location: The stream is in a very remote location away from industry or farms. Which filter would be the best choice for your situation, considering the purification efficiency of each?
	a)		b)
	c)		d)
