Standard Categorical Statements WS2 Answers 

1.  Translate into standard categorical form in two ways: beginning with the word "no" and beginning with the word "all."

...classes will not meet in May unless it is necessary to reschedule them.

Answer:

• a) no non-rescheduled classes are classes that will meet in May.
• b) All non-rescheduled classes are not classes that will meet in May.

2. Translate into standard form and defend the point that "rescheduled classes" is an undistributed term and explain what this means relative to this example: "Only rescheduled classes will meet in May."

"Only rescheduled classes will meet in May" translates to "All classes that will meet in May are rescheduled classes."

Regarding distribution (whether or not all members in a category are being referred to), rescheduled classes is an undistributed term, which means that there are other rescheduled classes for other times of the year; here rescheduled classes is just a slice of the pie as an undistributed term.
