Hi balvinder,
Thank you for your question. Let's tackle this question one problem at a time, and we'll figure out how to get to the correct answer.
Whenever a sentence indicates a comparison or contrast, the first thing to look for is parallel structure between the 2+ things being compared or contrasted. This sentence starts with "In contrast..." so we know this is a good place to start. Let's look at what two things are being contrasted and determine if they're parallel:
A: environmentalist's proposals / administration
B: environmentalist's proposals / administration
C: environmentalist's proposals / administration
D: environmentalist's proposals / administration's proposal
E: environmentalist's proposals / administration's proposal
Answers D & E are the only ones that use parallel structure, so let's get rid of answers A, B, & C.
Here are the main differences between answers D & E:
D. administration’s proposal
was a call for mandatory restrictions, which include
By saying "was a call," this indicates that the proposal called for these restrictions in the past, but may or may not call for them today. It may also confuse readers into thinking this proposal no longer exists. Therefore, this is an INCORRECT answer.
E. administration’s proposal
would call for mandatory restrictions on
This is the CORRECT answer because it uses parallel format and uses the clearer verb "would call" to show what restrictions the proposal currently contains.
