Understanding Grammatical Errors in Sentences

The question asks us to carefully read a sentence divided into three parts, labelled (a), (b), and (c), and identify if there is a grammatical error in any of these parts. If no error is found in any part, then the answer is (d).

Let's examine each part of the sentence:

The sentence is: This testing method requires (a) / one to fast overnight after which (b) / the fasting blood sugar level is measured. (c) / No error (d)

  • Part (a): "This testing method requires"
  • Analysis: The subject is "This testing method" (singular), and the verb "requires" agrees with the subject in number. This part appears grammatically correct.
  • Part (b): "one to fast overnight after which"
  • Analysis: This part follows "requires" from part (a). The structure "requires one to fast" is a common and correct usage, where "one" is the object and "to fast" is an infinitive phrase. "overnight" is an adverb modifying "fast". "after which" is a relative pronoun phrase connecting to the preceding action (fasting overnight) and introducing the subsequent event (measuring the blood sugar level). This part is also grammatically sound.
  • Part (c): "the fasting blood sugar level is measured."
  • Analysis: This clause describes what happens "after which" (after fasting overnight). "the fasting blood sugar level" is the subject. "is measured" is the verb in the passive voice, which is appropriate here as the blood sugar level is the recipient of the action (measuring), not the doer. This part is grammatically correct.

Upon reviewing all three parts, no grammatical error is found in any of the underlined sections (a), (b), or (c).

Therefore, the correct response is (d) which indicates "No error".

Revision Table: Common Sentence Error Types

Error Type Description Example of Error Correction
Subject-Verb Agreement Subject and verb do not agree in number (singular/plural). The dogs runs in the park. The dogs run in the park.
Verb Tense Errors Incorrect use of past, present, future tenses, etc. Yesterday, he goes to the store. Yesterday, he went to the store.
Pronoun Agreement Pronoun does not agree with its antecedent in number or gender. Each student should bring their own book. Each student should bring his or her own book.
Misplaced Modifiers A phrase or clause modifies the wrong word or phrase. She served cookies to the children on paper plates. She served cookies on paper plates to the children.

Additional Information on Sentence Structure

Understanding basic sentence structure is key to identifying errors. A simple sentence typically contains a subject and a predicate (which includes the verb). More complex sentences can include objects, complements, phrases, and clauses.

  • Subject: Who or what the sentence is about (e.g., "This testing method").
  • Predicate: What the subject does or is (e.g., "requires one to fast overnight after which the fasting blood sugar level is measured").
  • Infinitive Phrase: A phrase starting with "to" + verb, often functioning as a noun, adjective, or adverb (e.g., "to fast overnight").
  • Relative Clause: A clause beginning with a relative pronoun (like "which", "who", "that") or relative adverb (like "when", "where", "why"), adding more information about a noun (e.g., "after which the fasting blood sugar level is measured").
  • Passive Voice: The subject receives the action (e.g., "the fasting blood sugar level is measured"). The active voice would be "Someone measures the fasting blood sugar level."

In the given sentence, all these elements are used correctly, resulting in a grammatically sound sentence.
