A small group can be defined as a collection 3 to 20 people working interdependently to accomplish a task. However, research suggests that groups are most productive when they have how many members?

5 to 8 members.

Explanation:

In respect of the subject matter, Research is of the opinion that groups are most likely to be productive when they have between 5 to 8 members.

One of the reason for the above is that having limited members between 5 to 8 will give the members enough time to brainstorm and participate or contribute effectively

Another reason was that feed back from members can be gotten as early as possible. Not ambiguous like that of huge members

the correct answer is the first option "the bolkshevik revolution". the passage makes reference to many of important events that occured in the revolution, such as the assemblies, in this case the animals are gathered in an assembly after a protest, the murder of fellow partners, the speeches given by the leader of the revolution, among other aspects. the last choice is possible, but in this passage in particular it is not emphasized the fight between the characters, that is the two pigs, that represent lenin and stallin.

the answer is irony!
