Final answer:
In the sentence, the word 'Books' is incorrectly capitalized; common nouns like 'books' should only be capitalized if they're at the beginning of a sentence or part of a title.
Step-by-step explanation:
The word incorrectly capitalized in the sentence 'We like reading Books and listening to pop music.' is 'Books.' According to capitalization rules, common nouns, such as 'books', should not be capitalized unless they are the first word of a sentence or part of a title.
Proper nouns, on the other hand, are always capitalized. When referring to genres or general hobbies, the words remain in lowercase.
The word "Books" is incorrectly capitalized in the sentence. In standard English, only proper nouns, the first word in a sentence, and certain specific titles should be capitalized. Since "Books" is not a proper noun or the start of a title, it should be in lowercase.
Proper capitalization enhances readability and conforms to grammatical conventions. So, the corrected sentence would be: "We like reading books and listening to pop music." This adjustment ensures grammatical accuracy and maintains a polished appearance in written communication.
