The setting at the beginning of the story is a small town in russia in the pale of settlement in the 1906, a time of frequent pogroms . how does this setting affect the plot

There is no way to answer since I do not see any answer choices, but a subjective statement is a statment that is based on personal opinion. It is also not backed up with much evidence for the reason of that opinion.

Example:

"I can't stand pepporoni on a pizza."

This is someone's personal opinion, and it is not backed up with much reasoning. A more objective sentence would be, "I spit out the soggie, salty pepporoni." This sentence gives detailed reasoning and can be followed by the subjective sentence.
