I am not sure if anyone noticed, but don't we need a ";" after the independent clause - "Caribou are wary animals with excellent hearing," ?
Is comma sufficient to join two independent clauses?
If you stick a conjunction ("and", "so", "although", etc.) in front of an independent clause, the clause then becomes dependent. So there's no problem here at all: "caribou are wary animals with excellent hearing" is the independent clause, and the following clause -- beginning with "and" or "so" -- is dependent. A comma is no problem in this situation, and a semicolon would be incorrect.
I hope this helps!
Hi GMATNinja, this throws me off, everything after the comma starting with 'so...' in choices A, B, and C is an IC so I think that a semi-colon is appropriate, no?
You're right that the comma + "so" connects two independent clauses in (A), (B), and (C).
However, that doesn't mean that it is necessary to use a semicolon in those options. Semicolons are generally used
to link two independent clauses WITHOUT any conjunction between. For example:
CORRECT: I really love potatoes; they are splendid vegetables.
The use of a semicolon would be unnecessary if you added in a coordinating conjunction. For example:
INCORRECT: I really love potatoes; and they are splendid vegetables.
This second example is closest to the official question on this thread -- because "so" is a coordinating conjunction between two independent clauses, we don't need to use a semicolon as well.
There are circumstances in which you can properly use BOTH a coordinating conjunction AND a semicolon. For example, if there are commas embedded in both clauses and the sentence is difficult to interpret without the semicolon, then it may be appropriate to include the semicolon and conjunction. However, since the first clause here is relatively straightforward, a semicolon is not necessary in this sentence.
I hope that helps!
