Thanks a lot vikram

A good question to show that WHICH need not necessarily refer to the immediately preceding noun before comma. In such cases it will refer to the noun subject of the prepositional phrase before the comma. In this sentence, CHANGES IN TEMPERATURE is the prepositional phrase before comma and WHICH needs to refer to the CHANGESIN TEMPERATURE to retain the meaning. A and E choices have a modifier issue, which means that the modifier can refer to CHANGES IN SEA LEVEL and CHANGES IN TEMP.

IMO:D

IMO D

There are lot of problems in OG with not only ... but also usage ...

not only of/on (preposition) ... but also of/on (preposition) ...
not only damage (verb) but also destroy (verb) ...


I missed few problems considering only the not only but and not the remaining part . If there are any options having parallel structures for words following not only but also - watch out for them as well.
