This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Math reasoning
Prompt focus: If a country GDP is 500 billion dollars and it grows by 4 percent in a year, what is the new GDP?
Why the correct answer works
520 billion dollars
500 billion plus 20 billion equals 520 billion.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
4 percent of 500 billion is 20 billion. Adding to the original gives 520 billion dollars.
Simple analogy
Think of math reasoning like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
