Last chance for SAT on Oct. 6th><
Waiting for help!

1.(PSAT)
Pictures of vipers drawn on the walls of caves suggest that prehistoric hunters may have used snakes charms [for bringing] good luck.
The [] part is the right choice, but I looked up in my Longman dictionary and it says that there is the phrase "use sth for (doing) sth". Is it that the phrase is wrong in SAT?

2.(SAT)
Captive-bred whooping cranes have no parents to teach them migratory habits, [this fact explaining why they] must be led on their first migration by humans flying microlight aircraft.

Is the sentence correct if "this fact" is deleted?

3.(SAT)
A thick growth of sunflowers [standing ten feet tall, their brown heads drooped] over the fense with the weight of their seeds.
The correct answer is [stood ten feet tall, their brown heads drooping]
I can't see any difference in grammatical structure..

4.(SAT)
Intimacy, love, and marriage are three [different, if interrelated, subjects].
the correct answer is A, but I chose C[different subjects, whereas they are interrelated]
Why C is wrong?
I googled the question and one explanation is that the "if" in the original sentence means "even if". Is this explanation correct?

5.(SAT)
London [differs from] other cities, such as Paris and New York, [in that] its shopping areas are so [widely] spread out.
The right choice is E, no error.
I thought that "widely" is used to describe some abstract verbs and "wide" to some concrete verbs. Why it shouldn't be "wide" ( "extending over a vast area") here?

Thx!!!

2.(SAT)
Captive-bred whooping cranes have no parents to teach them migratory habits, [this fact explaining why they] must be led on their first migration by humans flying microlight aircraft.

If you drop "this fact" the participial phrase "explaining why they must .. " has no obvious noun to modify.

Thx!!!! And could you answer other questions?~

6.(PSAT)
The benefits [of] the new product [have] been carefully studied from the [prospective] of the consumer to ensure that it is marketed [effectively].
The answer is C. But why?

teteatete

1) "to bring" - otherwise the sentence has no verb and is a fragment.

2) answered.

3) The original sentence has a comma splice. The infinitive verb in the updated one, on the other hand, does not form a stand alone sentence. Basically the same idea as number one.

4) It's just correct structure. I can't understand the way you presented your question.

5) Adverbs are used to describe adjectives. Widely describes the adjective spread in this sentence.

6) Prospective is not the proper word in context. The answer is perspective.

I scored a 2370 on the SAT, with 800 (80MC) on the writing section.

4.(SAT)
"Intimacy, love, and marriage are three [different, if interrelated, subjects]."

Yes, the explanation that you found on the internet is correct.

The issue with your choice is that "whereas" is a subordinating conjunction that serves to express contrast between the idea in the independent clause and that in the dependent clause. It doesn't make sense to use whereas when the ideas are interrelated, and that's what choice (C) states: "whereas they are interrelated". An example of "whereas" in action is: "The Yoyos are winners whereas the Zozos are losers."

Alternatives to "if" are "and yet", "and still", etc.

Thank you guys!!o(*^▽^*)o
But I still cannot understand the explanation for the first question..
Why "use sth to do" is correct here but not "use sth for doing"?

One more from online course test6.
7. Jean Toomer was [not only] the author of Cane, a novel whose publication [has been viewed] [as marking] the beginning of the Harlem Renaissance, but also a respected advisor [among Quakers].
Choice E is correct.
I'm not sure if "view sb as doing sth" is correct.
