Answer:
The answer is letter D. correct.
Explanation:
This selection contains no run-on sentences. Run-on sentences happen when we put together two independent clauses without connecting them with proper punctuation and introductory words. Independent clauses contain a subject and predicate and express a complete thought on their own, without depending on other clauses.
The only option where a run-on could happen would be letter B. We have two independent clauses - followed by dependent ones, but they don't really matter here -, "I was shocked to learn that he had a hefty collection of hip hop saved on his MP3 player" and "I was shocked that he knew how to use the technology." However, they are properly connected with a semicolon and the adverb "furthermore". Therefore, we do not have a run-on. Options A and C would not allow for run-on's, since they do not present two independent clauses. The best option is letter d. Correct.
Main detail is the main point of your paragraph/essay. you want to be able to start and finish with that so it will remain within the reader thought for longer.
(We Brits have a saying "if a piece of literacy is stuck in your head, the writer has accomplished his or her goal" )
the supporting details are smaller points that correlate and support the main point. note that you should never start with a supporting point, nor should you ever end with one, it is simply there to extend and highlight the main detail. starting or ending with supporting details will ensure that the reader will almost instantaneously forget your essay and they may even find it boring because it doesn't show consistency.
D. I did not remember that fact until my older sister reminded me.
Among the sentences presented, this is the sentence that contains an adverb clause, "I did not remember that fact until my older sister reminded me." The adverb clause in this sentence is "until my older sister reminded me". An adverb clause is simply a part of the sentence that contains a subject and a verb with a subordinate conjunction. The subordinate conjunction do not allow the clause to have a complete meaning. An adverb clause also answers to the question how, when, where and why. In this case, the adverb clause answers to the question "how".
