Question

the text states that roads must be \big enough\ for all the cars and buses. what does this mean?
a the roads must be smaller than the sidewalks.
b the roads must be built so that motorcycles can go fast.
c the roads must be built so that cars and buses can move around safely.
d the roads must be straight and have no turns or curves.

Explanation:

The phrase "big enough" for cars and buses implies functionality for these vehicles. Option A is incorrect as it contradicts the idea (roads smaller than sidewalks). Option B mentions motorcycles (not relevant to cars/buses). Option D about straight roads with no turns is not related to being "big enough". Option C aligns with the idea that roads need to be built for cars and buses to move safely (which is related to being appropriately sized).

Answer:

C. The roads must be built so that cars and buses can move around safely.
