Q.1	A study analysed water samples from a polluted lake and found high levels of heavy metals such as lead and mercury. What is the potential impact of these heavy metals on the ecosystem of the lake?
	a) Heavy metals can accumulate in organisms and disrupt the food chain		b) Heavy metals can promote biodiversity and enhance ecosystem health
	c) Heavy metals have no effect on the lake ecosystem		d) Heavy metals can purify the lake water

Q.2	While analysing climate data from the past century, Sophie noticed a trend of increasing global temperatures. What correlation did Sophie find between the rise in global temperatures and the greenhouse effect?
	a) There was no connection between rising temperatures and the greenhouse effect.		b) The rise in global temperatures was caused by increased volcanic activity.
	c) The greenhouse effect was a contributing factor to the observed rise in global temperatures.		d) Human activity had no influence on the greenhouse effect or global temperatures.

Q.3	Sarah and Jake embarked on a fun adventure to explore a nearby wind farm. They were fascinated by the massive wind turbines spinning gracefully in the wind. What is the primary function of these wind turbines?
	a) Capturing wind energy to create artificial rainfall in the area.		b) Filtering air pollutants to make the environment cleaner.
	c) Using wind power to pump water from underground reservoirs.		d) Generating electricity by using wind to turn turbines connected to generators.

Q.4	Sarah made efforts to reduce waste and use recycled materials, what is most probably an example of her creative use of recycled items?
