provide ........for is correct.
E is more concise and it avoids the passive voice.
E it is.

2: Although women's wages are improving, Department of Labor statistics show that the ratio of their earnings with that of men have been roughly static since 1960.

A: with that of men have been
B: to that of men are
C: to those of men have been
D: with those of men is
E: to those of men has been

ratio of X to Y is correct.
"since 1960" reminds us of present perfect tense. Since " ratio" is singular , thus present perfect must be " has been".
I'm left with E.

E: Acquiring 828,000 square miles in the Louisiana Purchase of 1803, the United States bought it for about four cents an acre, more than doubling the country's size and bringing


There's no need to use "that" in A. It just made the sentence redundant.
B seems to lack the main verb and " it" in B is ambiguous.
E is redundant.
the positon of " for about four cents an acre" in D is not favored as it can be better if placed after " acquired 828,000 square miles"
C is concise and correct those mistakes of other choices.
Go for C.

1. C - same as laxieqv
2. E - 'ratio has been'. Also, we need 'those' to refer to earnings.
3. C
A - 'Which' has no clear referent
B - Awkward
D - 'The US for about' is awkward
E - 'Acquiring, the US bought it' doesn't sound good

Got to be E. A and B is undiomatic. C and D is awkward. only E fits how and when properly.

A: with that of men have been
B: to that of men are
C: to those of men have been
D: with those of men is
E: to those of men has been

Only C and E compares correctly. so we need to see the proper subject verb agreement. lets see what has been static? it is the ratio. Ratio is always singular. So has been will be the right choice.
so E is the correct choice.

Here I am stuck between C and D. Don't know which one to choose.

Question 2

- ratio of A to B is correct. -> A and D are out.
- 'to that' is not correct -> B is out.
- ' have been' is wrong as ratio is not plural -> C is out.
- Think of these two sentences to see which one make sense to you:
1) The ratio of green balls to red balls is 2:1
2) The ratio of green balls to red balls are 2:1

E is the best choice.

C. between A and C, C is better because "with the Louisiana Purchase in 1803" in C is much clearer than "in the Louisiana Purchase of 1803" in A. BDE are all have bad construction...
