when -ing form is not separated from the clause with the help of comma. it always refer to noun just before it.

> I left the office, rushing to catch the flight.

rushing refer to me.

Note: When separated with the help of comma, -ing form may/may not refer to noun just before it.

> The clown making noise in the car is ugly.
making is referring to clown.

Hope it helps.

A) weight which allowed
B) weight, which allows
C) weight which has allowed
D) weight that has been allowing
E) weight allowing

The correct answer as per Grockit.com is Option B. I chose answer E. I thought answer B is wrong because 'which' can not refer to "they expend over 70% less energy than homeotherms per pound of body weight" clause. So using 'which' doesn't make sense. Moreover in this sentence 'which' can't even refer to the nearest noun before comma.

Can somebody please tell me, how B is correct and E is incorrect? Grockit.com didn't give proper explanation to questions.
None of the Option seems correct...you are right regarding the issue related to WHICH, but Op E is also wrong as mentioned by the above poster. I was looking for some answer choice having COMMA + ING usage but as no such choice is given i believe none of the Op is correct. Please PM Vivian for explanation. I think she from Grockit.

A) weight which allowed
B) weight, which allows
C) weight which has allowed
D) weight that has been allowing
E) weight allowing...............All the 4 options refer that weight is allowing,which is incorrect

the clause 'they expend over 70% less engery' is an adverbial clause, so it does not
require the pronoun which to be placed right next to it

In E, the gerund allowing is modifying weight which is NOT the subject

I also think that none of these answers is correct. Can someone from Grockit please advise?
