Understanding the Meaning
The passage starts by giving us some background:
- First, we learn that Zydeco music came from the French Creole community in southwest Louisiana.
- Then we're told about one particular instrument that gives zydeco its special sound: the vest frottoir.
Now the third sentence tells us more about this instrument:
- "The vest frottoir ______ a wearable washboard..."
Now here's where we need to fill in the blank. Let's look at our choices:
- We're deciding between different verb forms: "have been," "is," "were," and "are."
What do we notice about the structure here?
- The subject is "The vest frottoir"
- This is one instrument - it's singular
- We're talking about a single thing
- The sentence is telling us what this instrument IS
- It's defining it: the vest frottoir = a wearable washboard
- This is a linking verb connecting the subject to its description
- Since we have a singular subject ("The vest frottoir"), we need a singular verb
Looking at our choices:
- "have been" - this is plural
- "is" - this is singular
- "were" - this is plural
- "are" - this is plural
So we need "is" to match our singular subject.
Now let's read the rest to see the complete picture:
- "that is played by rubbing spoons or bottle openers against it"
- This describes HOW you play this wearable washboard
- You rub spoons or bottle openers against it
The complete meaning: The vest frottoir is a wearable washboard that you play by rubbing spoons or bottle openers against it - and this is what gives zydeco music its unique sound.
The correct answer is B. is
GRAMMAR CONCEPT APPLIED
Matching Verbs to Their Subjects (Subject-Verb Agreement)
The verb in a sentence must match the number of its subject - if the subject is singular (one thing), the verb must be singular; if the subject is plural (more than one thing), the verb must be plural. This is called subject-verb agreement in grammar terms.
Singular subjects take singular verbs:
- The instrument is unique (not "are")
- One vest frottoir gives the music its sound (not "give")
- The vest frottoir is a washboard (not "are")
Plural subjects take plural verbs:
- The instruments are unique (not "is")
- Many vest frottoirs give the music its sound (not "gives")
- The vest frottoirs are washboards (not "is")
In our question:
- Subject: "The vest frottoir" = singular (one instrument)
- Verb needed: singular form
- Correct choice: "is" (singular present tense)
have been
✗ Incorrect
- This is a plural verb form that would work with plural subjects like "they" or "the instruments"
- It creates a subject-verb disagreement with the singular subject "The vest frottoir"
- You wouldn't say "The instrument have been" - you'd say "The instrument has been"
is
✓ Correct
Correct as explained in the solution above.
were
✗ Incorrect
- This is a plural past tense verb
- It doesn't agree with the singular subject "The vest frottoir"
- You wouldn't say "The vest frottoir were" - you'd say "The vest frottoir was" if you needed past tense
are
✗ Incorrect
- This is a plural present tense verb
- It creates a subject-verb disagreement with the singular subject
- You wouldn't say "The vest frottoir are" - you'd say "The vest frottoir is"
