Question

dealers sitting in the bazaar covered their pies, their cakes, and their pumpkin - rolls with their hands, like eagles protecting their young, if they but caught sight of a passing student.
source: taras bulba and other tales
in this sentence, bazaar means:
a restaurant where you serve yourself and pay a cashier
a street of small shops, especially in the middle east
an embankment built around a space for defensive purposes
a partitioned section within a larger enclosed area

Explanation:

The word "bazaar" is a term often used in the context of a market or a street with small shops. In the given sentence, dealers are sitting and protecting their goods (pies, cakes, pumpkin - rolls). A restaurant (where you serve yourself and pay a cashier) is more about food service in a specific setting. An embankment (built for defensive purposes) is a structure related to defense. A partitioned section within a larger enclosed area is a more general description. The most appropriate meaning considering the context of dealers and goods is a street of small shops, especially in the Middle East.

Answer:

a street of small shops, especially in the Middle East
