Well Waddaya Know IX

Last week's question and answer:
Q: Moshe's mother sent him to buy 20 items. He will remember:
The first items
2 (4%)
The last items
3 (7%)
Between 5 & 9 items
11 (26%)
All answers
6 (14%)
Answers 1 & 2
13 (30%)
Answers 2 & 3
7 (16%)

A: Responsible for the first items on the list is the "primacy" effect, and for the last items, the "recency" effect. The short-term memory holds on average between 5 and 9 items (George Miller and others), but these can be 5-9 large chunks/strings of information through a process called "chunking".
This week's question, which I feel will get more guesses than most, is up to the left.
