Example of invalid argument?

Question

Give an example of
1. An invalid argument with 2 TRUE premises and a FALSE conclusion
2. An invalid argument with 2 TRUE premises and a TRUE conclusion

Answer 1

There is no such thing as an invalid argument with true premises and a true conclusion. An argument is valid if and only if its impossible for the premises to be true and the conclusion false. So, if you have two true premises and a true conclusion, you have a valid argument. I think you might be talking about soundness in #2.
