N-Level Numeracy and Literacy Fundamentals 4 — Questions and Answers
Question 1: What does a bar graph show?
- The movement of something over time only
- Data compared using bars of different lengths or heights to represent values (Correct answer)
- A picture of a place

Correct answer: Data compared using bars of different lengths or heights to represent values
A bar graph uses rectangular bars to compare data across different categories. The height (or length) of each bar represents its value.
Question 2: What does it mean to 'skim' a text?
- Read every word carefully

Correct answer: Read quickly to get a general idea of the content without reading every word
Skimming involves rapidly reading a text to get the overall meaning or main points, without reading every word in detail. It is useful for quickly assessing whether a text is relevant.
Question 3: A recipe serves 4 people. How much of each ingredient do you need to serve 12 people?
- The same amount

A glossary is an alphabetical list of terms specific to a book or subject, with their definitions, found at the back of the book — useful for finding the meanings of technical words.
