I think C is the right answer as here we do not need to establish the sequencing hence use of verb "had" is not required..am i on the right track?

I think we do need a past perfect to state the intended series of related events. That is: Dropping out of school and then reaching the age of fifteen.
In my opinion thus, option D makes more sense.

Original sentence can be broken down as: Option (D):

Albert Einstein (main subject)

- had dropped out of school before he reached the age of fifteen (Action 1)

and (conjunction), not having received a certificate (verb-ing modifier modifying the succeeding clause, also makes sense with the doer),

- was not accepted into the Polytechnic school in Zurich. (Action 2)

Hi, could someone explain to me why the correct answer is B? I don't think the use uf past perfect "had dropped out" is necessary since the order of events its clear thanks to the "before".

Why option B is correct? The statement includes "before" which clearly states the occurrence of that event

Hello tatubis and medhawi,

We hope this finds you well.

Having gone through the question and your queries, we believe we can help resolve your doubts.

When the chronology is clear because of terms such as "before/after/when/earlier/later"…or because of clear mention of dates, using the past perfect tense is not required, but the use of the past perfect is not incorrect either, in such cases.

All the best!

ExpertsGlobal5 thanks for the reply! If past perfect tense is not necessary why would A) be incorrect though?

Hello tatubis,

We hope this finds you well.

The issue here is that there are more than two events taking place in this sentence - Einstein dropping out of school, Einstein reaching the age of fifteen, and Einstein not being accepted into the Polytechnic school. Thus, although "before" indicates the chronology of the first two events, it does not do so for the chronology between Einstein dropping out of school and Einstein not being accepted into the Polytechnic school, so past perfect is needed to illustrate the order of those two.

We hope this helps.
All the best!

(A) dropped out of school before he reached the age of fifteen and, without a certificate, was
(B) had dropped out of school before he reached the age of fifteen and, without a certificate, was
(C) dropped out of school, without a certificate, before he reached the age of fifteen and, was
(D) had dropped out of school before he reached the age of fifteen and, not having received a certificate, was
(E) had dropped out of school before he reached the age of fifteen and, without a certificate, were

I see there are two events happening in the past:

Albert Einstein -> dropped out of school
-> not accepted into college

what happened first? because he didn't attend the school, he hadn't received the certificate and therefore he couldn't get into college

So we need past perfect.

A & C are out.
E has 'were' -> out

(B) had dropped out of school before he reached the age of fifteen and, without a certificate, was
(D) had dropped out of school before he reached the age of fifteen and, not having received a certificate, was

B feels better.
