Because the body adapts more readily to lengthened days than to shortening them is why most people experience less severe “jet lag” when traveling westward than when traveling eastward.


(A) Because the body adapts more readily to lengthened days than to shortening them is why most people experience less severe “jet lag” when traveling

(B) The body adapts more readily to lengthened days than to shortened days, with the result that most people experience less severe “jet lag” when traveling

(C) Because the body adapts more readily to lengthened days than to shortened ones, so most people experience “jet lag” less severely when they travel

(D) Because the body adapts more readily to lengthening days than to shortening them, most people experience less severe “jet lag” when they travel

(E) The body adapts more readily to lengthening days than to shortening them, so most people, as a result, who experience “jet lag” less severely when traveling





_________________

lengthened days is must parallel to shortened days

non underlined portion mentioned clearly is than when traveling eastward

so, the underlined portion must be parallel to non underlined portion.

when traveling westward than when traveling eastward looks better.


so, only option a, b and e does it.

among the options.

in A and E , lenghtened days to shortened days is parallelism not maintained.


so option B is correct.


apart from above error analysis, in option C usage of Beacuse is dependent clause,

it follow with independent clause. after comma usage of so becomes dependent clasue. so it is run on sentence and both usage of beacuse and so for reason
is redundancy.


option E usage of jet lag less severly usage is awkward.

It is OK to refer to an entire group (here "body") by using the definite article "the". Here "the" does not refer to a specific body but bodies of all human as a group.

The eye is our most valuable sense organ. ..correct.
