Question

1. select the verb that makes the sentence most grammatically correct. by mid-october, when the world series has played, the weather is uncomfortably cool for baseball fans in some places. played. is played, is playing,

Explanation:

The sentence refers to a recurring, scheduled event (the World Series in mid-October) that follows a regular pattern. For habitual or scheduled events, the passive simple present tense is correct here because the World Series is the recipient of the action (it is played by teams). "Is played" matches this context, while "played" (simple past) would refer to a single past instance, and "is playing" (present continuous) describes an ongoing action right now, which does not fit the general, annual timing of the event.

Answer:

is played.
