Identify the adjective, choose the correct sentence, and identify the correct sentence structure.

An adjective modifies a noun. In the sentence, "brave" describes the noun "officer."

The correct option is c).

• a) Officer (noun)
• b) Received (verb)
• c) Brave (adjective)
• d) Award (noun)

The adjective is $\boxed{\text{c) Brave}}$.

For a third-person singular subject like "He" in the present tense, the auxiliary verb "does" is used, not "do." Therefore, "doesn't" is correct. Also, after "didn't" (did not), the base form of the verb is used (know), not the past tense (knew).

The correct option is b).

• a) He don't know the suspect (Incorrect: "don't" should be "doesn't")
• b) He doesn't know the suspect (Correct)
• c) He didn't knew the suspect (Incorrect: "knew" should be "know")
• d) He don't knew the suspect (Incorrect: "don't" and "knew" are both wrong)

The correct sentence is $\boxed{\text{b) He doesn't know the suspect}}$.

This question asks for the correct sentence structure. The standard structure for a simple past continuous sentence is Subject + auxiliary verb (was/were) + present participle (-ing form of verb).

The correct option is c).

• a) Running the suspect was (Incorrect structure)
• b) The suspect running was (Incorrect structure)
• c) The suspect was running (Correct structure)

The correct sentence structure is $\boxed{\text{c) The suspect was running}}$.

When reporting direct speech, a comma typically precedes the opening quotation mark, and the punctuation mark (like a period or question mark) goes inside the closing quotation mark. The first word of the direct speech is capitalized.

The correct option is c).

• a) The officer said stop. (Missing comma and quotation marks)
• b) The officer said, stop. (Missing quotation marks)
• c) The officer said, "Stop". (Correct punctuation)
• d) The officer said "Stop" (Missing comma before quote, period should be inside)

The correctly punctuated sentence is $\boxed{\text{c) The officer said, "Stop"}}$.

For compound nouns like "commander-in-chief," the main noun is pluralized. In this case, "commander" is the main noun.

The correct option is b).

• a) Commander-in-chiefs (Incorrect: "chiefs" is pluralized)
• b) Commanders-in-chief (Correct: "commander" is pluralized)
• c) Commander-ins-chief (Incorrect)
• d) Commander-in-chiefes (Incorrect)

The plural of "commander-in-chief" is $\boxed{\text{b) Commanders-in-chief}}$.

This question asks for the odd word out. "Arrest," "detain," and "jail" all refer to holding someone in custody or restricting their freedom. "Release" means to set someone free.

The correct option is d).

• a) Arrest (To take into custody)
• b) Detain (To hold in custody)
• c) Jail (To imprison)
• d) Release (To set free)

The odd word out is $\boxed{\text{d) Release}}$.
