First, focus on the modifying phrase that starts the sentence. Whenever you see an introductory phrase followed by a comma, you're probably being tested on modification.

Here, the information before the comma describes California. Accordingly, we need "California" right after the comma: eliminate (a), (b) and (c).

Now we have to decide between (d) and (e). The biggest difference is after the comma at the end of the sentence.

(d) has "a drop more than twice as great as that" and (e) has "more than twice as great as that".

Just like the modifying phrase at the beginning of the sentence did, the modifying phrase at the end of the sentence has to match what's immediately on the other side of the comma. The problem with (e) is that "more than twice as great as that" could refer to "60" instead of to the drop. From the original sentence (our guide for meaning), we know that we want the after-modifier to refer to the drop, not the number, so eliminate (e).

(d) is the only one left, choose it!

Question: Modifying phrase

by parimi001 » Sat Feb 16, 2008 10:10 pm
Stuart, If this is not considered as a stupid question, why is this phrase "A decade after initiating the nation's most comprehensive and aggressive anti-smoking program" modifing California instead of cigarette consumption???

Thank You,
Venkat

Venkat, but how can cigarette consumption INITIATE a program?

Only California (i.e. the legislative body) can initiate a program.

INCORRECT: After turning off the faucet, the sink was emptied.

A sink can't turn off the faucet, like cigarette consumption can't initiate a program.

CORRECT: After turning off the faucet, JOHN emptied the sink.

The agent is JOHN. In the sentence the agent is California.

does that help any?

I think everyone forgot to check the redundancy here...on this i eliminated A,C, and E.
then on modification I eliminated B.
