Grade 7 · Reading · Page 2 of 3

DIRECTIONS: Three sentences that ARE evidence, in the same order.
1.
Of the 4,000 people who started the app last year, 12% finished the course.
2.
The new design uses 40% less steel than the bridge it replaces, which carries the same load.

  1. The third impostor quotes a real expert who is genuinely distinguished. Explain why "so you cannot trust experts" is the wrong lesson to take from it.
  2. Write a fourth impostor of your own — a sentence that looks like evidence and is not — then write the repaired version underneath it.
