Question

Which word in the sentence, if any, should be followed by a comma? The tide is very low which is typical for this time of day. A. low B. typical C. tide D. There is no error in comma usage.

Answer 1

In general, the comma shows that the words immediately before the comma are less closely or exclusively linked gramatically to those immediately after the comma than they might be otherwise . (Wikipedia)

The tide is very low , which is typical for this time of day.

Answer A

Answer 2

-- The comma should come after the word "low".

-- The behavior of the tides as implied by the sentence is completely
incorrect.  This may be the reason that the sentence shows up in the
<English> category rather than in <Physics>.
