I am taking an introductory argumentative philosophy course at my university and could use some help!

Right now we are dipping our toes into categorical syllogisms and I'm having a lotta lotta trouble.

Here are my homework problems - I'm having trouble figuring any of them out. I have to look up definitions for each one and then double check it and then sometimes I still get the answers wrong. Does anyone have any advice or tips or a chart or well, anything to help out?

True or False?

(1) A valid argument may have a false conclusion. If so, provide an example and explain why

this example does not violate the definition of validity. If not, explain why not.

(2) All arguments with false premises and a false conclusion are valid. If so, explain why. If

not, explain why not in terms of an example.

(3) All arguments with false premises and a false conclusion are invalid. If so, explain why. If

not, explain why not in terms of an example.

(4) An argument with true premises and a false conclusion must be invalid. If so, explain why.

If not, explain why not in terms of an example.

(5) An argument with true premises and a true conclusion must be sound. If so, explain why.

If not, explain why not in terms of an example.

(6) If an argument is unsound, then it must have false premises. If so, explain why. If not,

explain why not in terms of an example.

(7) A sound argument must have a true conclusion. If so, explain why. If not, explain why not

in terms of an example.

(8 ) If an argument is invalid and it has true premises, then it must have a false conclusion. If

so, explain why. If not, explain why not in terms of an example.

(9) All unsound arguments are invalid. If so, explain why. If not, explain why not in terms of

an example.

(10) If an argument is valid and it has true premises, then it must have a true conclusion. If so,

explain why. If not, explain why not in terms of an example.
