The counts describe the full Grind1600 bank. The Free plan unlocks the first 5 questions in each parent domain; the live question-bank API and attempt routes enforce that boundary.
These questions pair a short passage with a table or graph and ask which data point correctly completes the passage's argument. Every answer choice cites real numbers — but usually only one both reads the graphic accurately AND serves the passage's specific claim.
Work in two passes: first eliminate choices that misread the graphic (wrong row, wrong year, wrong magnitude — check each number against the table), then among accurate readings, pick the one that completes the argument's logic. The passage's final sentence before the blank tells you exactly what the data needs to show.
The available Command of Evidence (Quantitative) samples use graphics that are best rendered in the authenticated question bank. Open Information and Ideas practice to use the questions allowed by your current tier. The Free plan remains limited to the first 5 questions in this parent domain.

Choosing the quotation or finding that most directly supports, illustrates, or weakens a stated claim or hypothesis.
Inferences
