Mayor: To keep our neighborhoods clean, every street in town will be swept at least once a month. If a neighborhood needs more frequent sweepings, due to excessive dirt from major construction for example, that neighborhood will be qualified for interim sweepings. All requests for interim sweepings from qualified neighborhoods will be satisfied immediately.

Summary

Every street in town will be swept at least once a month.

If a neighborhood needs to be swept more frequently than once a month, that neighborhood will be qualified for interim sweepings.

All requests for interim sweepings from qualified neighborhoods will immediately be satisfied.

Notable Valid Inferences

If a qualified neighborhood requests interim sweepings, that neighborhood’s streets will be swept more than once a month.

If a neighborhood is excessively dirty from major construction, that neighborhood will be qualified to receive sweepings more frequently than once a month.

If a neighborhood with excessive dirt from major construction requests interim sweepings, that neighborhood’s streets will be swept more than once a month.

A
All neighborhoods in which construction is under way are qualified neighborhoods.

Could be false. The stimulus states that a neighborhood is qualified if there is excessive dirt from major construction, not merely if there is any type of construction at all. Maybe minor construction does not lead to excessive dirt!

B
All qualified neighborhoods will get their streets swept more than once a month.

Could be false. The stimulus does not say that qualified neighborhoods that do not request interim sweepings will receive such sweepings (but it also doesn’t say that they won’t). Maybe some qualified neighborhoods will not submit a request and thus will only be swept monthly!

C
No street will be swept more than once a month unless it is located in a qualified neighborhood.

Could be false. The stimulus doesn’t state that being a qualified neighborhood is the only way to receive more frequent sweepings. As far as we know, “qualified neighborhood that requests interim sweepings” is a sufficient, not necessary, condition of receiving interim sweepings.

D
A qualified neighborhood that requests an interim sweeping will have its streets swept more than once a month.

Must be true. If a neighborhood is qualified for interim sweepings and it requests such sweepings, that request will be satisfied. In other words, that neighborhood will have its streets swept more than once a month!

E
No street in an unqualified neighborhood will be swept more than once a month even if the neighborhood requests it.

Could be false. The stimulus doesn’t state that being a qualified neighborhood is the only way to receive more frequent sweepings. As far as we know, “qualified neighborhood that requests interim sweepings” is a sufficient, not necessary, condition of receiving interim sweepings.
