Grammar questions, than and then?

<p>I have two grammar questions from the blue book involving the use of than.
pg 540 #27
The novel Pride and Prejudice by Jane Austen (was once) more (widely read) and was (more popular) in high schools in the United States (than Charlotte Bronte). No error</p>

<p>pg 661 # 28
(In) the United States, the industrial (use of) plastics (is) greater (than steel), aluminum, and copper combined. No error</p>

<p>Answers are both D but I really cannot figure out why. Any help would be appreciated.</p>

<p>In the first one, it is comparing the book by austen to bronte, not bronte's book.
It should be than Bronte's book.</p>

<p>Than = comparing 2
Then = 3+</p>

<p>Wow that really cleared the air. Thanks</p>

<p>Actually elaslawek, your first explanation works for both. The use of ___ is greater than (the use of)... because otherwise you are comparing the use of something to the elements</p>

<p>Couldn't agree with PaPa H more!
When it comes to COMPARISON, we only have "than" as a comparative conjunction (preposition); "then" does not work, in every case.
Regarding the two above examples, what the SAT tests are COMPARISON and PARALLELISM.</p>

<p>Oh I see so it should be something like the industrial use of plastics is greater than the uses of steel, aluminum, and copper combined?</p>

<p>^ Yup. Exactly.</p>
