Hi Deepti,
Here is the sentence:
The world wildlife fund has declared that global warming, a phenomenon most scientsts agree to be caused by human begings in burning fossil fuels, will create havoc among migratory birds by altering the enviroment in ways harmful to their habitats.
a) A phenomenon most scientists
agree to be caused by human beings in burning fossil fuels,...agree to be is wrong. Moreover, caused by human beings in burning fossil fuels is just awkward.
b) a phenomenon most scientists agree
that is caused by fossil fuels burned by human beings,....what does "that" refers to in this sentence. Also the sentence sounds like global warming is caused by fossil fuels itself and not the process of their burning.
c) a phenomenon that most scientists agree is caused by human beings's burning of fossil fuels....
this sentence is correct as it is and conveys the meaning.
d) which most scientists
agree on as phenomenon caused by human
beings who burn fossil fuels,....D is wordy and awkward.
e) which most scientsts
agree to be a phenomenon caused by fossil fuels burned by human beings...again change in meaning as mentioned in B
D and E are just plain wrong. "Which" only refers to the noun before the
