All engineering students should learn mechanics, mathematics and how to do computation. Which of the above underlined parts of the sentence is not appropriate?
I II III IV
Identifying Grammatical Parallelism Error
The question asks to identify the inappropriate part in the sentence regarding what engineering students should learn. The sentence structure involves a list of items that should be grammatically parallel.
The sentence is: "All engineering students should learn mechanics, mathematics and how to do computation."
Analyzing Sentence Structure
The sentence lists three things students should learn. Let's identify the grammatical form of each item in the list:
- Item 1: 'mechanics' - This is a noun.
- Item 2: 'mathematics' - This is a noun.
- Item 3: 'how to do computation' - This is a phrase starting with an infinitive construction ('how to do').
For a list to be grammatically correct, all items should have the same form (e.g., all nouns, all verb phrases). In this sentence, the first two items are nouns, but the third item is not a noun.
Determining the Inappropriate Part
The lack of parallelism lies in the phrase 'how to do computation'. The options refer to potential segments of the sentence:
- I corresponds to 'mechanics'.
- II corresponds to 'mathematics'.
- III corresponds to 'how to do'.
- IV corresponds to 'computation'.
The phrase 'how to do computation' breaks the parallel structure required for the list. While the entire phrase is problematic, the question asks to identify one specific inappropriate part among the options. The noun 'computation' (IV) is part of the non-parallel phrase. If the list were corrected to include only nouns, it might read "...mechanics, mathematics, and computation." However, the presence of 'how to do' preceding 'computation' makes the structure incorrect. Given the options, and identifying 'computation' as the final element presented in a non-parallel manner, it is considered the inappropriate part in this context.
Therefore, the part labelled IV ('computation') is not appropriate in the context of the list's parallel structure.
