Sentence Correction

thanks in advance!

1st question:

"as large or larger than" is redundant. By saying that something is "at least las large" implies that it could be as large or larger than what it is being compared to.

2nd question:

This is testing parallelism. You have to match (structually) "found" which in this cases acts as an adjective modifying "animal". "Resembling" acts as an adjective also modifying "animal".

In first Question,

Most of them is the Correct idiom this elminates d & e
a--as large or larger than is dedundant and unidiomatic
b-- same as above
c---is correct which expresses the idiom as large as and Most of them correctly

but can any one tell me why Circling is used

In second question,

and that -- is unidiomatic hence(a,b,e)
in D--it is redundant

hence I go for C

Please correct me if I am wrong

Sirikesav, you are right in your assessment of the questions. "Circling" is used because it is what the planets were doing when they were discovered. Even though it's in the past tense, it is an action that is happening over time. Therefore the imperfect tense should be used -- it matches the present tense for the verb "to circle".

Thank you for your help guys!
