Passage Summary: Everyone at a certain convention belongs to the party. Some of those people are government officials, and every government official there is also a speaker.

Reasoning: All convention delegates are party members; some of these delegates are government officials; and all government officials present are also speakers.

Analysis: This is a formal logic puzzle. We know that the group 'government officials at the convention' is a subset of 'delegates,' and 'delegates' is a subset of 'party members.' Therefore, those government officials are definitely party members. Since those same officials are also speakers, we can conclude that there is an overlap where some people are simultaneously party members, government officials, and speakers.
