Final answer:
The irrelevant detail to the topic sentence 'My favorite pair of jeans are beat up and worn out,' is the brand of the jeans (F), as it does not describe their condition.
Step-by-step explanation:
The student is asked to identify the irrelevant detail in relation to the topic sentence about their favorite jeans. The topic sentence is "My favorite pair of jeans are beat up and worn out." All the details provided, except for one, are related to the condition of the jeans which supports the topic sentence. After reviewing the choices, the irrelevant detail that does not pertain to the jeans being "beat up and worn out" is letter F, which states the jeans are "made by the Levi's company". This detail is about the brand, not the condition of the jeans, and therefore does not contribute to the development of the main idea.
