Answer:
C, a wireless keyboard and a 24" LED monitor.
Explanation:
Desktop computers shouldn't need a foldable or split-style keyboard. A wireless keyboard is better than a gaming keyboard cost wise. A 24" LED would be more cost efficient and have good screen resolution.
I actually believe the correct answer is an adverb clause modifying was.
A is incorrect because the first clause is subordinate; B is incorrect because there is no noun clause in this sentence; C is incorrect because the word modifying school is an adjective, but not an adjective clause; this leaves us with D. We can see the adverb clause 'when the Little Red Schoolhouse began to give way to the consolidated school in the 1920s' which modifies the verb 'was.'
I believe the answer is D
A plot is, basically, the events that make up a story or are part of a story. The plot can have very little to very many events. It's kind of like the storyline.
