Sentence Correction: Parts of Speech - Articles

After searching for a practical substitute to the inconvenience and expenses entailed in owning a car, a large amount of consumers chose bicycles as a method of transport within the central business district, thus lowering congestion, pollution, and noise levels.

This answer choice is grammatically incorrect. The article amount of can describe non-count nouns only whereas the noun consumers is a count noun.

What helps us identify this mistake is the following Stop Sign:

much, (a) little, less, the amount of

This answer choice is grammatically incorrect and repeats the original Parts of Speech error. The article amount of can describe non-count nouns only whereas the noun consumers is a count noun.

What helps us identify this mistake is the following Stop Sign

much, (a) little, less, the amount of

Although this answer choice corrects the original Parts of Speech error by replacing the article amount of with number of, it creates Redundancy with the wordy phrase and in this way.

Although this answer choice corrects the original Parts of Speech error by replacing the article amount of with number of, it creates a Dangling Modifier. The sentence begins with a modifier: After searching for a practical substitute to the inconvenience and expenses entailed in owning a car. A modifier should be placed right next to the noun it describes. The only noun that this modifier can logically modify is consumers. The noun consumers, however, is quite far from the modifier that describes it. Therefore, it seems like bicycles are searching for a practical substitute to the inconvenience and expenses entailed in owning a car.

What helps us identify this question as a Dangling Modifier question as well as identify the mistake is the following Stop Sign:

A modifier, characterized by all of the following:
1. Verb+ing or Verb in 3rd form
2. Separated from the rest of the sentence by a comma
3. Appears at the very beginning of the sentence

Whenever you see this Stop Sign, focus on the modifier: check whether the noun right after the modifier is indeed the noun that the modifier describes. If it isn't - you've found your mistake.

Excellent work!

The article amount of can describe non-count nouns only whereas the noun consumers is a count noun. This answer choice corrects the original Parts of Speech error by replacing the article amount of with number of.
