Until quite recently, American presidents lived in a world in which the public and private realms of their lives were largely seperate, and the press cooperated in maintaining the distinction, and Americans judged national leaders without receiving, or expecting, intimate information about them.
A..
B. where the press cooperated in maintaining the distinction, and where
C. for the press cooperated to maintain the distinction and
D. the press cooperated to maintain the distinction, for
E. in which the press cooperated in maintaing the distinction, and in which

I choose B because where would relate to the "realms"..what about E? is "in which" appropriate??

People have discovered the principles of solar energy whenever fuel becomes scarce and expensive but will forget them every time a new source of cheap energy is developed.
A. ...
B. have discovered the principels of solar energy whenever fuel has become scarce and expensive but they forget
C.discovered the principles of solar energy every time fuel becomes scarce and expensive, forgetting
D. discover the principles of solar energy every time fuel became scarce and expensive, but they forget
E. discover the principles of solar energy whenever fuel becomes scarce and expensive but forget

==> is there a difference between "discovered" and "have discovered" (couldnt you use the present participle because people could have discovered from the past into the present?
Also,...if you add "they", after "but" so it becomes "but they forget" (like D), is it wrong?

I think you can answer both questions without difficulty if u
know the following constructions

Independent clause;Independent clause
Independent clause, coordinating conjunction Independent clause

(common coordinating conjunctions : and, but, or, so, yet)
Independent clauses stand alone as a sentence

I would chose D for both questions

1st sentence:

I choose B. This sentence refers to the topic where vs. which

where is used mainly for places while which is an adajetive. Examples:

The house where I grew up is for sale

The house which I like the most is the white one.

2nd. sentence:
I choose E since you need teh present tense here.

I would have chosen D and E...but now I see why E is a correct choice in the first sentence
