The librarian has not entered the new books in the …

Step 1: Analyze the question The sentence is: "The librarian has not entered the new books in the ..........". We need the word that names the record a library uses to list its books.

Step 2: Explain the concept Each option has a specific meaning:

• List: a general series of items. It is too broad and not specific to libraries.
• Directory: a book or listing of names, addresses, and phone numbers (like a telephone directory), or a folder on a computer. It lists people or organisations, not library holdings.
• Catalogue: a complete, organised list of items, such as books in a library, usually arranged by author, title, or subject. This is the standard library term.
• Roster: a list of people's names, such as duty or team members. It is not used for books.

Step 3: Solution Librarians "enter" new books into the catalogue so that readers can find them. This is the technical term for a library's record of its books, and it fits "entered ... in the" better than the other options. "List" is grammatically possible but is less precise and not the best answer. A directory and a roster are for people or organisations.

Step 4: Answer The correct option is C. catalogue.

Step 5: Exam tip Learn the "specific-place" vocabulary pairs:

• Library → catalogue
• Telephone/addresses → directory
• Staff or team duty → roster
• Hospital/class attendance → register

When several options seem possible, pick the most specific and context-appropriate word. WASSCE usually rewards precision.
