Q.1 Q.2 Q.3 Q.4 Q.5 Q.6 Q.7 Q.8 Q.9 Q.10

Q.1

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?

Q.2

At Greenway Middle School, the cafeteria decided to track food waste over a week. The given table represents the daily amount of food wasted. If the school wants to reduce food waste by 20%, how much food, in kilograms, should they aim to save each day?

Day Food Waste (kg)
Monday 2.8
Tuesday 3.5
Wednesday 4.2
Thursday 5.1
Friday 3.9
Saturday 3.2
Sunday 2.6

Q.3

In the quest for cost-effective, safe, and carbon-neutral energy sources, various technological options have been under scrutiny for their potential to provide a seamless transition.
Among the listed energy technologies, which option is often regarded as a solution capable of enabling a smooth transition to affordable, safe, and carbon-free energy sources?

1. Natural gas
2. Biomass energy
3. Solar energy

Q.4

In a future scenario where climate change drastically alters global weather patterns, which land biome would likely experience the MOST drastic and irreversible changes?

Q.5

A community introduced a new technology that reduced water usage for irrigation by 20%. Initially, 1,000 hectares of land were irrigated using 200,000 cubic meters of water.

What volume of water would be saved annually if this technology is applied to all 1,000 hectares?

Q.6

In a remote village, access to electricity is limited. The government aims to introduce affordable and clean energy sources to improve living conditions. Considering the village's geographical isolation, unreliable grid connections, and the need for sustainable solutions, which approach would be the most effective and practical for providing immediate access to clean energy?

Q.7

Maya and Ethan observe vibrant coral reefs, but they notice patches of white, bleached skeletons amidst the colourful corals.
Choose the MOST likely factor triggering coral bleaching.

Q.8

A group of researchers is discussing the causes and effects of climate change during a conference. They aim to pinpoint the accurate relationship between a specific human activity and its consequent impact on the environment.
