Difficulty: MediumSubject-Verb Agreement

The construction of traditional Polynesian voyaging canoes requires not only deep ecological knowledge but also exceptional craftsmanship. The wood selected from native forests, along with fibers from coconut husks used to lash the hull, are carefully cured over several months to ensure durability at sea.

Which of the following options is the correct form of the underlined verb?

  1. A
    NO CHANGE
  2. isAnswer
  3. C
    was
  4. D
    have been

Answer

is
The correct option is the singular present-tense verb 'is'. The subject of the sentence is 'wood,' which is singular. The phrase starting with 'along with' is parenthetical and does not change the subject's number. A singular verb is required to maintain subject-verb agreement, and the present tense must be maintained to match the context established by the verb 'requires' in the first sentence.

Step-by-Step Solution

1
Identify the subject of the verb in question.
The subject is the singular noun 'wood.'
The phrase 'along with fibers from coconut husks used to lash the hull' is a parenthetical prepositional phrase that modifies the subject but does not make it plural.
2
Determine the correct verb number (singular vs. plural) and tense.
The verb must be singular and in the present tense ('is').
Subject-verb agreement requires a singular verb for the singular subject 'wood,' and the passage is written in the present tense as established by 'requires' in the first sentence.
