Q.4	Consider the city planning graph below, showing the distribution of bike lanes, pedestrian pathways, and green spaces in a city. Which area is most sustainably developed?
	a) Area A		b) Area B
	c) Area C		d) Area D

Q.5	Amelia observed that during heavy rains, one part of the city experienced flash floods and drainage issues due to excessive concrete, while another region with abundant green spaces remained relatively unaffected. Why did the area with green spaces fare better?
	a) The city's overall topography favored water runoff in green spaces.		b) Concrete areas had more efficient drainage systems in place.
	c) Green spaces effectively absorbed excess water, preventing flooding.		d) The presence of concrete minimised water absorption, causing flooding.
