The tense shift you will not hear: SAT verb sequence
The passage has been in the past tense for four sentences. The blank offers a present-tense verb that reads perfectly well in isolation. That is the trap.
Why it happens
You evaluate the blank as its own sentence, where any tense sounds fine. Tense consistency is a property of the passage, and the passage is the thing you stopped reading once you found the blank.
See the trap
"In 1911, Hiram Bingham reached the ridge. He photographed the terraces and ___ his notes that evening."
✗ The trap: "writes his notes" — a present-tense verb inside a past-tense narrative.
✓ The fix: "wrote his notes" — matching "reached" and "photographed".
How to actually fix it
- Before choosing, name the tense of the sentence before the blank.
- Name the tense of the sentence after it.
- Only depart from that tense if the sentence itself signals a time shift ("by then", "today", "since").

When is the perfect tense the answer?
When the sentence marks one action as finishing before another: "By the time he arrived, the crew had left." If there is no such ordering signal, the simple past is usually right.
