Hello
GMATNinjaI have question about option C. In Option C "An Area about the size of Colorado", author is comparing AREA with Size of Colorado. It is correct option.
In another SC on comparison --https://gmatclub.com/forum/laos-has-a-land-area-about-the-same-as-great-britain-but-only-four-mil-107156.html you mentioned for option D that the comparison( Area vs Size) isn't ideal: we're comparing the "land area" of Laos to the "size of Great Britain." That's not great.
I think both questions contradict for Area vs Size comparison. Could you please advise which comparison is correct ?
Thanks,

Interesting question! The difference between the two sentences is the presence of the phrase "comparable to" in the Laos example. To see why this is important, consider the following:
1) Tim's weight, after a year of relentless anxiety, is 129 pounds.
In this case, we're giving a precise measurement of Tim's weight. Perfectly logical.
2) Tim's weight, 129 pounds, has decreased significantly since the start of the pandemic.
This time "129 pounds" functions as a modifier describing Tim's exact weight. Again, this makes sense. So far, so good.
3), Tim's weight, comparable to 129 pounds, has decreased significantly.
Now something funky seems to be going on. As the first two examples show, there's no problem giving information
about weight in terms of pounds. But it seems strange to
compare Tim's weight to pounds, as if "pounds" isn't a unit of measurement to describe the weight, but rather, is a second kind of weight that we might contrast with the first.
Back to the SC examples.
Quote:
1) The number of acres overseen by professional farm-management companies has grown from 48 million to nearly 59 million, an area about the size of Colorado.
Notice that this example is more like the second one above: "the size of" modifies the area. You could replace the "size of Colorado" with whatever the actual number is -- say, 60 million acres -- and the sentence would make perfect sense. The area is about 60 million acres. Seems fine.
Contrast that with the other sentence you noted:
Quote:
2) Laos has a land area comparable to the size of Great Britain.
This one is more like the third example, because of the phrase "comparable to." Again, try the exercise of replacing "the size of" with an actual number -- say, 500 square miles. Now we have that funky meaning again. We can write that the land area
is 500 square miles, but it's odd to write that the land area is
comparable to 500 square miles, as if we're comparing a land mass to a unit of measurement, rather than using the unit of measurement to provide information
about the land area. So unlike the previous example, this one is no good.
Takeaway: do not attempt to memorize anything you just read! It won't help you. Instead, use this discussion as an example of how to think through a question, using subtle differences in context and logic to steer you.
I hope that helps a bit!
