As per MGMAT SC past perfect form should be used only when the sequence of events is not clear otherwise.

Choice E does not use past perfect but its still quite clear that Roentgen's experiment was done 1 year before Bequerel's experiment. Need some clarification.

Look at this awful example; 
The main clause is : In 1896, Henri Bequerel found.
The sub clause is : that uranium salts emitting penetrating radiations similar to those which Roentgen produced only a year earlier with a gas discharge tube.

There is no verb in this sub- clause, rendering it a fraction. All the choices suffer this problem; This is because, the sentence has been turned a complex sentence, by the use of the relative pronoun that. To make the sentence passable, the present participle emitting should be made emitted

Bxn C & E :

C. Uranium salts emitted radiations similar to RADIATIONS (= those)............................that Roentgen had PRODUCED :

( THAT aptly connects the dot = The uranium radiation was similar to X ( what is this X ? ) = THAT helps us in understanding = X was a radiation , it was produced by Rontgen a year earlier

E. Uranium salts emitted radiations similar to RADIATIONS (= those )............................Roentgen PRODUCED ( Doesn't it give an incomplete sense )

1 : ...................Radiations THAT X had produced earlier

2 : ..................Radiations X produced earlier

guess 2 explains the intent/ completes the structure in a better way

Analogy :

1. The films were similar to films............ Spielberg produced a year back

2. The films were similar to films.............THAT Spielberg had produced a year back

"THAT' helps me to zone in on 2 = THAT in C scores over E ; Leading to C , my take

The critical thing here is whether we use a past perfect - had produced - as in C , or a simple past tense- produced- to describe what Roentgen produced only a year earlier. Here it may be noted that the time marker –earlier-unequivocally makes out that it was a deeper past event and hence we may not use a past perfect after all. A simple past might suffice as some have expressed, even quoting MGMAT. 
But GMAT thinks otherwise ( sometimes?) : Look at the following GMAT PREP example:

Retailers reported moderate gains in their November sales, as much because  of their sales of a year earlier being so bad as that  shoppers were getting a head start on buying their holiday gits.
1) of their sales of a year earlier being so bad as that
2) of their sales a year earlier having been as bad as because
3) of their sales a year earlier being as bad as because
4) their sales a year earlier had been so bad as because
5) their sales of a year earlier were as bad as that

Here also the time marker - earlier -has been explicitly stated. But still D is the official answer, which uses the past perfect. Would anyone argue against the OA?

I Think because it's reported speech we have to change the simple past to to past perfect. Here is the link from Mike at Magoosh. https://magoosh.com/gmat/2013/sequence-o ... orrection/

Jayati23 · Answer

Looking at the event sequencing :
E1 : "found" the salts
E2 : that "emmitted"
E3 : "produced" earlier

E1 and E2 are unrelated so no sequencing required and hence simple past is okay
E2 and E3 are related where E3 is earlier, hence sequencing is required . E3 needs to be expressed using past perfect "had produced"
only option C is correcting this.
