Understanding Subject-Verb Agreement in Sentences

The question asks to identify the grammatically correct phrase to replace "bear out" in the sentence: "If the evidence bear out the charge, he may be sentenced to death."

This sentence is a conditional sentence, specifically a Type 1 conditional, which talks about a possible future event depending on a present condition. The structure of a Type 1 conditional sentence is typically: If + simple present tense, ... simple future tense (or modal + base verb).

Let's look at the 'if' clause: "If the evidence bear out the charge". The subject of this clause is "evidence". "Evidence" is a singular, uncountable noun.

In the simple present tense, a third-person singular subject requires the verb to end in '-s' or '-es'. For example:

• He walks.
• She sings.
• It rains.
• The evidence supports.

The verb phrase here is "bear out". When the subject is "evidence", which is singular, the simple present form should be "bears out". Therefore, "bear out" is incorrect.

Analyzing the Options

Let's examine the provided options to see which one correctly uses the simple present tense form for the singular subject "evidence":

1. bears out: This is the simple present tense form of "bear out" for a singular subject ("evidence"). This fits the requirement for the 'if' clause of a Type 1 conditional sentence.

2. bore out: This is the simple past tense of "bear out". This is not the correct tense for the 'if' clause in this Type 1 conditional structure.

3. was born out: This is the passive voice, simple past tense of "bear out". The sentence requires an active voice verb, and the tense is incorrect for a Type 1 conditional 'if' clause.

4. has born out: This is the present perfect tense. The past participle of "bear out" is "borne out", not "born out" (which relates to birth). Also, the present perfect is not the correct tense for the 'if' clause in this specific Type 1 conditional structure.

5. No correction required: As established, "bear out" is grammatically incorrect with the singular subject "evidence" in the simple present tense. Therefore, a correction is required.

Based on the rules of subject-verb agreement in the simple present tense and the structure of Type 1 conditional sentences, the correct phrase to use with the singular subject "evidence" is "bears out".

The corrected sentence would be: "If the evidence bears out the charge, he may be sentenced to death."
