Question

complete the sentence with the word that best fits the overall meaning and tone. \has anyone ______ his alibi, or should we still consider him a suspect?\ the detective asked. denounced announced corroborated

Explanation:

• "Denounced" means to publicly declare to be wrong or evil, which doesn't fit the context of checking an alibi.
• "Announced" means to make known publicly, which is not relevant to the idea of verifying an alibi.
• "Corroborated" means to confirm or give support to (a statement, theory, or finding), which is appropriate as the detective is asking if anyone has confirmed the alibi.

Answer:

corroborated
