Question

statements: no letter is a fax. all messages are faxes. conclusions: i. no message is a letter. ii. at least some faxes are messages. only 1 follows only 2 follows either 1 or 2 follows both 1 and 2 follow neither follows

Answer 1

We can get the meaning of each statement.

No letter is a fax = This means that if it is a letter then it is not a fax.

All messages are faxes = This means that if it is a message then it is a fax.

The meaning of the conclusions are as follows:

No message is a letter = This implies that if it is a letter then it is not a message.

This conclusion is true since a message is a fax but a fax is not a letter and therefore a message is also not a letter.

At least some messages are faxes = This means that not all messages are faxes.

This conclusion is not true since the statement says all messages are faxes and not at least some messages.

The correct answer is thus :

Only one follows.
