Do u have similar kinds of rules list so that it can be easy to
solve these kinds of problem by implementing that rules.
Yes, we do - but it's not something I can post on the web. It's our entire SC book - the Sentence Correction Strategy Guide.
When the phrase "endurance and consistency" is used as the subject, we have to match it with a plural verb ("endurance and consistency" = a compound subject, which is always plural). Eliminate B and C.
When using an opening noun modifier (starting a sentence with some words that are not a complete sentence and are referring to some noun in the sentence), we have to put the noun in question right after that comma.
Known as a great typist, Joe got the job.
In choice E, we start with an opening noun modifier ("known as The Iron Horse") but the nouns following the comma are "endurance and consistency." No bood. "Lou Gehrig's" is not functioning as a noun in the sentence - it is a possessive, functioning as an adjective describing the nouns "endurance and consistency." Eliminate E.
D is problematic for two reasons. First, "the reason... is because of..." is awkward - you could even argue redundant. Second, we don't actually know that his "endurance and consistency" are the
reason he is known as The Iron Horse. The original sentence does not say that - it just says his endurance and consistency are legendary, while adding that he was also known as The Iron Horse. Eliminate D.
That leaves us with A.
