Fill in the blank: Raidi Qayyim noticed that soil pollution on his family's farm (Old Money) can lead to reduced ______ yields.

• crop

• mineral

• water

• air

Answer explanation

Soil pollution negatively affects the quality of soil, which is essential for growing crops. Contaminated soil can lead to reduced crop yields, making 'crop' the correct choice. The other options do not directly relate to soil pollution.

Noise pollution is particularly significant in urban areas with high traffic, industrial activities, and ________.

• wildlife

• human activity

• agriculture

• silence

Answer explanation

Noise pollution in urban areas is primarily caused by human activity, including traffic and industrial operations. This makes 'human activity' the most relevant choice, as it directly contributes to the overall noise levels.

Which of the following activities can generate large volumes of radioactive waste?

• Farming

• Mining

• Fishing

• Tourism

Answer explanation

Mining can generate large volumes of radioactive waste due to the extraction of minerals like uranium and thorium, which are naturally radioactive. Other activities like farming, fishing, and tourism do not produce significant radioactive waste.

Haryth and Puteri Nur Syasyabila are discussing the various sources of air pollution in their city. They are very diligent and putting their phone on DND mode.They want to know what is a major source of air pollution according to the transportation category.

• Mining

• Power generation

• Domestic activities

• Transportation

• Agricultural practices

• Industrial activities

Answer explanation

Transportation is a major source of harmful gases and particulates due to vehicle emissions, which contribute to air pollution. Other activities like domestic, agricultural, and industrial practices also release pollutants, but transportation is particularly significant.

Poobhalan and Vumasangari are discussing different modes of transportation for their school project on sustainable mobility and also their future life. Which of the following is NOT a mode of sustainable mobility?
