Must be FalseDiff: Hard
Logic Breakdown
Passage Summary: In Calistan, car sales were steady for a while, and during that time, Marvel doubled its sales and took over more of the market. Later, after new rules were made, Marvel kept selling the same high number of cars, but their percentage of the total market dropped significantly.
Reasoning: The stimulus provides data on car sales: for ten months, total market sales were flat while Marvel's sales and share grew; then, for three months, Marvel's sales stayed high but its market share dropped.
Analysis: This is a 'Must be False' question rooted in basic set theory and percentages. Market share is a ratio: Marvel's sales divided by the total market sales. If Marvel's sales (the numerator) stayed exactly the same, but their market share (the result) went down, the total market sales (the denominator) must have increased. Therefore, any statement claiming that total car sales in Calistan stayed the same or decreased during those final three months is mathematically impossible and must be false.

Unlock Full Passage15.If the statements above are true, which one of the following CANNOT be true?
Correct Answer
A
If Marvel’s sales (M) are constant while Marvel’s share drops substantially, total sales (T) must have increased, so other companies’ total sales (T − M) must have increased. Choice A says other companies’ sales decreased after the standards, which contradicts the implied increase. Hence it cannot be true.
