Explanation:

Question 19

The question is about memory strategies. Indexing, chunking, encoding, and interference are concepts in memory (Psychology, a subfield of Social Science). Rehearsing a memory after mastery relates to encoding (or rehearsal encoding). Wait, no—wait, the options: Wait, actually, the correct term for rehearsing to strengthen memory (even after knowing) is related to encoding? Wait, no, maybe I misremember. Wait, the options: A. Indexing (organizing memory), B. Chunking (grouping info), C. Encoding (processing into memory), D. Interference (disrupting memory). Rehearsal is a type of encoding (maintenance rehearsal). So the correct option is C? Wait, no, wait the question: "Rehearsing a memory even after you think you know it well is an effective strategy"—this is about encoding (or rehearsal). Wait, maybe the correct answer is C. Encoding. Wait, no, maybe I made a mistake. Wait, let's recheck: Indexing is like categorizing memory. Chunking is grouping. Interference is when memories interfere. Encoding is the process of putting info into memory. Rehearsal (including over - rehearsing) is part of encoding. So the correct option is C. Encoding.

The question is about "smart" drugs/drinks/bars and their effect on memory. Scientific consensus: Most "smart" drugs/drinks have little evidence of improving memory. Option A: Most scientists don't recommend as there's little evidence. Option B: There is very little evidence they improve memory (correct). Option C: No, they don't greatly improve short - term. Option D: Not shown to cause memory loss. So the correct option is B.

Answer:

C. encoding
