The others are fine.

Correct answers:

1. (b) Presidents'
To determine the correct answer, we should consider that "wives" refers to the wives of multiple presidents. Therefore, we should use the plural possessive form of "presidents," which is "Presidents'."

2. (a) well-behaved
To determine the correct answer, we need to consider that "well-behaved" is a compound adjective modifying the noun "child." In compound adjectives that come before a noun, we should use hyphens to connect the words. Therefore, the correct answer is "well-behaved."

3. (b) all-state
To determine the correct answer, we need to understand that "all-state" is a compound adjective modifying the noun "tennis meet." Again, compound adjectives that come before a noun should be connected with hyphens. Therefore, the correct answer is "all-state."

4. (b) Lucia and Maria's
To determine the correct answer, we should consider that the sentence is referring to the mother belonging to both Lucia and Maria. In this case, the possessive form is created by adding an apostrophe and an "s" to the last name mentioned. Therefore, the correct answer is "Lucia and Maria's."

5. (a) 1930's
To determine the correct answer, we should consider that we are referring to a specific decade, the 1930s. In this case, we use an apostrophe before the "s" to indicate a contraction of the second digit in the decade. Therefore, the correct answer is "1930's."

6. (a) Colonel
To determine the correct answer, we should consider that "Colonel" is a military rank and should be written in full as it is when introducing someone formally. Therefore, the correct answer is "Colonel."
