Notice "more" ....the right structure is " more .....than", thus eliminate A and B.
C : that and which both are used to begin a noun clause...using one is correct, but not for both.
D doesn't state clearly what is compared to what
E is the best.

A and B repeat two " is" ( dunno if you made an error when underlying the right part or not ) ....easily eliminate them.
E is out coz we need an adjective after "is"
C is perfect with correct structure " so.....that"

1. E is the best choice. Others sound unidiomatic or wordy.
A is wrong in using 'he therefore' - Doesn't connect with the sentence

2. E is best. We need 'more money was removed in July than in any other month'

3. C. We need 'so reflective' to maintain parallelism. Btw B and C, i would Choose C
because 'were it' in B has no clear referent. But, a 'is' before 'reflective' would have been nice. Don't know why!

4. B. But D also appears to be correct. This is a controversial one, been discussed a lot of times before.

A (E sounds good)
E
C
E (I think this one can't be B because we need of the 5 million)

Question 1

E is the best choice. The rest all have very awkward sentence constructions.[/b]

Question 3

A. awkward

B. 'is so reflective' is not appropriate

C. awkward sentence construction

D. 'or' changes meaning of hte sentence

E. reflects so that little of the polar ice melts during the summer; if it did

E is the best choice.

B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.

I have chosen E because 'Have appeared' // 'Have Vanished' whereas in B it is 'appeared' and 'Have vanished'
