Multiple choice Hard memory-consolidation ~120s

Exercise 6.2. Episodic memory holds four episodes, oldest first: e1 (t=1, importance 0.6), e2 (t=2, 0.9), e3 (t=3, 0.6), e4 (t=4, 0.3). Cosine similarities: e1–e3 = 0.95 and e2–e4 = 0.92; every other pair is below 0.5. Following the `consolidate(threshold=0.9)` docstring, which episodes survive?

A e2 and e3 B e3 and e4 C e1 and e2 D e1, e2 and e3

Hints are free to take and they are counted. A correct answer after two hints moves your mastery less than one without — which is the honest way to score it.
