Idiom: in each of the following questions, choose the alternative which best expresses the meaning of the idiom or phrase. Feather in one's cap

Introduction / Context:
This idiom question tests whether you know the figurative meaning of the expression feather in one's cap. Idioms often come from old customs or cultural practices and their meanings cannot be guessed simply by translating the individual words. You must remember the established sense used in modern English.

Given Data / Assumptions:

• Idiom: feather in one's cap.
• Options: Discrimination, A new and additional distinction, Hunting, Bird watching, A serious failure.
• The idiom is applied when someone gains an honour, achievement, or credit that adds to their reputation.

Concept / Approach:
Historically, warriors or hunters sometimes wore feathers in their caps as marks of bravery or success. Over time, the phrase feather in one's cap came to mean a notable achievement or honour that adds to a person's prestige. It is a positive expression, highlighting something that makes someone proud. The option that best captures this is A new and additional distinction, that is, an extra credit or honour on top of what they already had.

Step-by-Step Solution:
Step 1: Recall the context where this idiom is used, such as Winning the award is another feather in her cap. Step 2: Understand that it refers to a notable achievement that improves a person's record or reputation. Step 3: Compare the options and identify which one refers to an honour or distinction. Step 4: Select A new and additional distinction as the most accurate paraphrase of the idiom.

Verification / Alternative check:
Insert each option meaning into a sample sentence. Earning a gold medal was a real feather in his cap becomes Earning a gold medal was a new and additional distinction for him, which preserves the sense. The same sentence cannot sensibly be completed with Discrimination, Hunting, Bird watching, or A serious failure without changing the meaning entirely. This confirms that the idiom expresses something to be proud of, not something negative or unrelated like bird watching.

Why Other Options Are Wrong:

• Discrimination: Refers to unfair treatment or, in a positive sense, the ability to judge, but it does not convey the idea of an honour.
• Hunting: A literal activity involving chasing animals; not the figurative meaning of the idiom.
• Bird watching: Again, a literal hobby, chosen only because of the word feather, but unrelated to achievement.
• A serious failure: The exact opposite of what a feather in one's cap represents.

Common Pitfalls:
Because the idiom mentions a feather, some learners mistakenly associate it with birds, bird watching, or hunting. However, the historical image is that of a decorated cap symbolising success. The safe method for idioms is to remember them with example sentences, not by literal word association. In exams, always choose the option that fits the idea of an additional honour, which in this question is clearly A new and additional distinction.

Final Answer:
Correct option: A new and additional distinction.
