Which choice completes the text so that it conforms to the conventions of Standard English?
included
includes
including
will include
Choice C is the best answer. The convention being tested is the use of nonfinite verb forms within a sentence. The nonfinite present participle "including" is correctly used to form a participial phrase that supplements the main clause "he patented many inventions," listing several of Spikes’s patented inventions.
Choice A is incorrect because the finite past tense verb "included" can’t be used in this way to supplement the main clause "he patented many inventions." Choice B is incorrect because the finite present tense verb "includes" can’t be used in this way to supplement the main clause "he patented many inventions." Choice D is incorrect because the finite future tense verb "will include" can’t be used in this way to supplement the main clause "he patented many inventions."
