George’s personal diary and album formed the basis for his book about the places he had visited.
  1. the basis for his book about the places he had visited.
  2. the basis for his book regarding the places he had visited.
  3. the basis of his book about the places he visited.
  4. the basis of his book about the places which he had visited.
  5. the basis of his book about the places he had visited.

OA: [spoiler](C)[/spoiler]
I am not sure about the authenticity of the OA.
I have found this question in this forum, but would like to have some more clarification about the choices. Please justify your answer.

Can you please explain what is wrong with [spoiler](E)[/spoiler]? I can perhaps eliminate [spoiler](D)[/spoiler] because of the use of "which", as GMAT most probably prefers to use "where" to indicate location.

This is a great GMAT SC question.

The past perfect is used to imply that something happened in the past BEFORE something else happened in the past (using the simple past), as in:

I had packed my bags when the phone rang.

This sentence implies the packing happened first.

However, if the sentence has other context clues, then we no longer need the past perfect to tell us it happened first:

Right before the phone rang, I packed my bags.

The words "right before" tell us the time relationship, so we can put both in the simple past.

In this GMAT sentence, I feel it would require a rather large logical leap to think that George could write a book reflecting on the experiences he had in the future. Thus, answer (C) works. We may use the simple past.

Answer (E) uses the past perfect, which leaves us wondering, "He had visited these places... before what?" There is no other action in the past tense that his visits could have preceded, making the simple past preferable.

Hope that helps.

Isn't there a problem of using pronoun for possesive noun.
Shouldn't it be "George had visited".

Thanks Jose for the explanation!

Yes, I agree with you. But none of the answer choices give us option to rectify that. So, for this question, it is out of scope!

IMO : A

I think X formed the basis for Y is more suitable than X formed the basis of Y

HAD usage is justified I feel.
I am on a break !!

can one of the instructors comment on this? is it formed the basis of OR formed the basis for?

Also, the explanation for C isn't convincing. In this particular sentence, the vists happened before he started writing his book so makes sense to use past perfect.

I agree with Martin. The book is based on places "he visited". These visits have already occurred, so the inclusion of "had" to form "he had visited" is unnecessary.

"Basis of " works perfectly fine .
for e.g. "the basis of this drink is orange juice" meaning "the most important or necessary part of something"

Are we saying that C is wrong? Prefer the tenses to be in simple past unless unless you need to differentiate the timing of 2 independent events

diary is something which is written along with a process...usage of "had" makes it imperative that the diary or traveling happened in some sort of sequence ...which is not true...as he may have visited California ...wrote something..visited Alaska ..then wrote more in his diary....

So concurrent action cannot be shown using the past perfect ..

my2 cents.
