Use the right form of verb to fill in the blanks.
a) will be b)would be c)would have been d) will have been
(I think the answer is option b). Am I correct?)

Will be

I think the answer is.. Would have been....

To determine the correct answer, we need to understand the grammar structure used to indicate a hypothetical condition.

In this sentence, "If it rained heavily" is the beginning of a conditional statement. Conditional statements typically consist of two parts: the "if" clause, which presents a condition, and the main clause, which states a consequence.

The main clause in this sentence is "the reservoirs," which requires a verb in the appropriate tense. Since the conditional statement is presented in the present simple tense ("If it rained heavily"), we need to use the past simple tense to indicate the consequence.

Now let's analyze the answer options:

a) will be - This is in the future tense, not correct as we are talking about a hypothetical consequence based on a past condition.
b) would be - This is the correct answer as "would be" is the past simple tense indicating the hypothetical consequence based on the past condition.
c) would have been - This verb tense is used for unreal past conditionals, which is not suitable in this context.
d) will have been - This verb tense is used for future perfect tense, which is not appropriate in this context.

Therefore, considering the analysis provided, your answer is correct. The correct answer is option b) "would be."

You are correct.
