Sentence Correction

One reason why more young people lose their virginity during the summer than at other times of the year undoubtedly is because school vacations give adolescents more free time.

(A) One reason why more young people lose their virginity during the summer than at other times of the year undoubtedly is because

(B) If young people lose their virginity more during the summer than other seasons, it is undoubtedly because

(C) One undoubtable reason that young people lose their virginity more during the summer than other times is

(D) One reason more young people lose their virginity during the summer than at other times of the year is undoubtedly that

(E) Young people lose their virginity more often during the summer undoubtedly because, for one reason,


Whats the diff between A and D ?

Please explain.

A uses "one reason why x happens is because of y happens"

D uses " one reason x happens is that y happens"

A is wordier, needlessly uses reason why...because. the word reason takes care of the why/because

Why is C wrong ??
"One undoubtable reason that young people lose their virginity more during the summer than other times is..."

is it because THAT incorrectly modifies REASON ??

However, in D, the think the positioning of the adverb, UNDOUBTEDLY is terribly wrong!
"One reason more young people lose their virginity during the summer than at other times of the year is undoubtedly that.."

C uses a structure: "the reason that x happens is y happens". the "that" is misplaced.

also C is not parallel. "more during the summer than other times" . we need "at" between "than" and "other times"

it makes better sense in D: "one reason x happens is that y happens". also parallelism is maintained.

D

Hi ,

I guess usage of because just before the comma makes this choice absurd

Young people lose their virginity more often during the summer undoubtedly because, for one reason

If we remove the phrase between the commas, then this choice might make sense

IMO - B

Choice B is concise. Also "more" should modify "summer". It must not modify " young people". This is the reasoning i used to choose B.

Also A and E are ruled out. One reason and Because are redundant. Either one can be used to explain the reason.
