In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should
acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.
(A) in part that their steers should acquire certain characteristics
(B) in part for the acquisition of certain characteristics in their steers
(C) partly because of their steers acquiring certain characteristics
(D) partly because certain characteristics should be acquired by their steers
(E) partly to acquire certain characteristics in their steers
This is a tricky question. Most people would fall for answer choice (D), but it's really (E)
. Let me show you how I think through this question:Step 1:
Notice "in part" is underlined and there are variations in the answer choices. So is it "in part" or "partly"?---well let's look continue looking at the rest of the sentence and you'll see the keyword "and" and then the word "partly" next to it. Step 2:
Notice "partly" is not underlined--which means this is cannot be changed. So, what needs to be changed is "in part." Therefore, you can eliminate answer choices (A) and (B) since they both use "in part."Step 3:
Now that you know it's either (C), (D), or (E) because of STRUCTURAL reasons, let's take a look at the MEANING of the sentence.
Ask yourself what are the two reasons the author is trying to communicate?
You're talking about cross breeding. Why are people doing more cross breeding?Step 4:
Well, you know "partly because crossbreeding is said to provide hybrid vigor.
Here the reason is that crossbreeding is said "to provide hybrid vigor.
So your second reason must be consistent with that!Step 5:
With (C), I see "partly because of their steers acquiring certain characteristics
"--which is not consistent with the second half of the sentence.Step 6:
With (D), I see "partly because certain characteristics should be acquired by their steers
" which does not have words in the form of "to + verb"Step 7:
But with (E), I see "partly to acquire certain characteristics in their steers
"--which is consistent with "to provide hybrid vigor.
Remember to look at the MEANING of the two reasons you are talking about. Don't simply see the word "partly because" and automatically assume the answer must be (D)!!
Hope that helps.
