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.

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

-- 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>.
