Question

Clouds dump around 100 billion gallons of water on rainforests each year. How much rain is evaporated from the rivers, lakes and surface of rainforests each year?
a. around 100 billion gallons
b. unable to tell from the information given
c. significantly less than 100 billion gallons
d. significantly more than 100 billion gallons

Answer 1

Answer:

b. unable to tell from the information given

Explanation:

We have only been given the amount of water rainforests receives in a year. No other information has been given. So also, we cannot make any further assumption and deduction from the information provided to us. In order to know the amount of water evaporated in a year, we should have been given the rate of evaporation in the rainforest. We cannot deduce the amount of water evaporated from this data.

Answer 2

Answer:

Letter B is the correct answer.

Explanation:

Based on the given information it is impossible to make that deduction. It's necessary to remember that the rain that falls on a place (the rainforest, in this example) doesn't always evaporate from the same place. Other factors (like if the location mentioned is close to the ocean) should be taken in consideration to determine an approximate answer, and they are not provided in the question.
