That vs. Which 
1. A testmagic tip: GMAT almost always (I say almost always because I've seen two questions that did not follow this rule, but the rule was violated in all five answer choices) wants you to put a comma before which. In other words, if you see which without a comma before it, it's probably wrong.

If the person you're talking to, or the person who's reading what you've written, needs that extra bit of information to know which noun you're referring to, we say that that extra information is non-restrictive. This word doesn't really describe the function clearly, so many teachers say that this information is “extra."

On the other hand, if you need that information to know which noun you are talking about, we say that the information is restrictive. Again, this word is not really a good choice for clarity, and many teachers use the term "necessary information" instead

We need a comma before non-restrictive clauses and phrases but it is not needed before restrictive clauses and phrases.

Both the sentences below are correct according to GMAT, but have different meanings.
• Please go into the room and get me the big book, which is mine. (Ex: of non-restrictive)
• Please go into the room and get me the big book that is mine. (Ex: of restrictive)

2. “That” almost always refers to a restrictive clause or phrase and “which” to a non-essential phrase. 
Ex: The bananas that I left on the table have gone bad.
Bananas, which are high in potassium, are considered ideal for dieting.

3. Also, the relative pronoun “which” should be used to refer to a noun and not an idea or an action presented in an entire clause. (Ex: Q.49, Q.78 from OG)
Q.78: The root systems of the most flowering perennials either become too crowded, which results in loss of vigor, and spread too far outward, producing a bare center. -> Use of “which” is incorrect.

4. Omitting “that”
• You can omit “that” in a relative clause when the subject of the clause is different from the word or phrase the clause refers to. Thus, you can say either 
The book that I was reading (or) 
The book I was reading

• You can also omit “that” when it introduces a subordinate clause 
Ex: I think we should try again.

• You should NOT omit “that”, however, when the subordinate clause begins with an adverbial phrase or anything other than the subject:
Ex: She said that under no circumstances would she allow us to skip the meeting. 
 The book argues that eventually the housing supply will increase. 
This last sentence would be ambiguous if that were omitted, since the adverb eventually could then be construed as modifying either argues or will increase.
