Which of the following statement is not correct in reference to intelligence…

Concept: Intelligence tests are classified by their mode of administration and content into three broad types: verbal tests (language-based, and conducted either individually or in groups), non-verbal tests (using pictures, diagrams, and figures instead of words), and performance tests (a form of non-verbal testing that uses concrete materials or manipulative tasks, such as assembling pieces or blocks). Non-verbal and performance tests share one defining purpose: they measure intelligence without requiring the ability to read or write, so that illiterate adults, young children, and people across language barriers can still be tested fairly.

Application: Checking each statement against this framework:

• Alexander's Pass-along Test asks the test-taker to assemble a set of pieces into a picture without using any language — this is a textbook example of a performance test, so the statement describing it as one is accurate.

• Verbal tests are indeed conducted in both formats — a one-to-one interview-style test counts as individual administration, while a paper-and-pencil test given to a whole classroom counts as group administration — so this statement is accurate.

• Because performance and non-verbal tests are built around visual-spatial and manipulative tasks rather than reading or writing, literacy is not a requirement for taking them — an illiterate person can complete a performance test just as capably as a literate one. This statement, which claims the opposite, does not hold up.

• Non-verbal tests do rely on pictorial and figural material — patterns, diagrams, and images — specifically so that a test-taker's intelligence can be judged independent of language, so this statement is accurate.

Cross-check: If performance tests truly required literacy, they would offer no advantage over verbal tests and would fail their core purpose of testing populations who cannot read or write. Since performance and non-verbal formats were developed precisely to remove that literacy dependency, the statement claiming illiterate people cannot take a performance test is the inaccurate one — which is what the question is asking for.
