Q1:

The miser gazed ...... at the pile of gold coins in front of him.

A avidly

B admiringly

C thoughtfully

D earnestly

ANS:A - avidly

Earnestly and Avidly are slightly related to each other as per this sentence. But where as earnestly has a meaning like "seriously towards something" and Avidly means "having keen interest to do something". So avidly is the answer.
