1.B
2.A

1 - yes

2 - no

On 1, "a" is the correct choice. The word congressman need not be capitalized unless it is a title, or is is a specific congressman. Such as in Congressman Dufus. But in text, congressmen are a dime a dozen, not specific nor capitalized.

To determine the correct capitalization in each sentence, you need to follow these rules:

1. Capitalize the first word of a sentence.
2. Capitalize proper nouns (names of specific people, places, organizations, etc.).
3. Capitalize titles when they are used as part of a name or when they precede a name.

Now let's apply these rules to each sentence:

1. In sentence A, "Congressman" is capitalized correctly because it is used as part of a title before a name ("African-American Congressman"). In sentence B, all capitalization is correct because "Congressman" is capitalized correctly and "African-American" is also a proper noun and is therefore capitalized.

Therefore, the correct answer is B for sentence 1.

2. In sentence A, "congressman" is not capitalized correctly because it should be "Congressman" since it is used as a title before a name ("Congressman Rainey"). In sentence B, all capitalization is correct because "Congressman" is capitalized correctly.

Therefore, the correct answer is A for sentence 2.
