Asked in Premeth Test 49 — EnzymesModerate

Find the Error.A couple of my friends(A) has planned(B) to open(C) a travel agency, but they(D) have failed.

Correct answer: B. Has planned

  • A. A couple of my friends
  • B. Has planned
  • C. To open
  • D. But they

Explanation

The phrase 'A couple of my friends' is considered plural, which means the verb that follows should also be plural. Thus, 'have planned' is the correct form to use instead of 'has planned.' The other options are accurate in their grammatical structure: 'A couple of my friends' correctly indicates multiple individuals, 'to open' is an appropriate infinitive phrase following the verb, and 'but they' correctly refers back to the plural noun 'friends.' Therefore, the error lies specifically in the verb form used in option B.

About Enzymes

Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
