BlackTom AI · Accepted Answer

A verb string is a predicate unit consisting of one or more verbs (auxiliaries, modals, or a single finite verb plus the main verb) that form the verbal complex of a clause. Count one verb string per clause's verbal complex, whether it contains a single verb or a combination of auxiliary/modal + main verb.

Step-by-step clause analysis and verb-string identification:
1. "Lyonel didn’t believe" — The negative auxiliary did (contracted in didn’t) plus the main verb believe form a single verbal complex for this main clause. Verb string 1: didn’t believe.
2. "he should ask" — Modal should + base verb ask form a verbal complex in the embedded clause. Verb string 2: should ask.
3. "whether he was invited to the party" — Passive auxiliary was + past participle invited create the verbal complex of this embedded subordinate clause. Verb string 3: was invited.
4. "because, after all, it was also his house." — The copular verb was links the subject it to the predicative noun phrase his house; this single finite verb constitutes a verbal complex for this clause. Verb string 4: was.

Intermediate note on contraction: didn’t = did + not, but did + believe together function as one verb phrase (one verb string) rather than two separate strings.

Why the correct answer is 4:
- There are four clauses each with its own verbal complex identified above; each complex counts as one verb string.
Why other options are incorrect:
- 1: grossly undercounts—there are clearly multiple clauses with separate verbal complexes.
- 2 and 3: undercount because they fail to count either the passive "was invited" or the copular "was" (or both).
- 5: overcounts; splitting contracted forms or miscounting auxiliaries as separate strings would produce this erroneous total.

Final confirmation: the sentence contains 4 verb strings, matching the provided answer 4.
