Question

In an interview last month, the rebels estimated that a few hundred of their fighters had been trained over the past two years, and they received close to two million dollars worth of ammunition, guns, and heavy artillery during the same time period.
A) had been trained over the past two years, and they
B) were trained over the past two years, and they had
C) were trained over the past two years and they have
D) had been trained over the past two years and that they had
E) had been trained over the past two years and that they have

Answer 1

Answer:

D) had been trained over the past two years and that they had

Step-by-step explanation:

In the context, the sentence speaks of something that happened in the past, so 'had been' is required and also it speaks of parallelism of events, as an estimation is being made so,  parallelism should be maintained.

Hence, option (D) satisfies the two requirements. And eliminate option A, B, C and E.

Thus, (D) is correct.
