1 is wrong. Please try again.

Suppose that Barbara gives you a valid argument. Must her conclusion then be true?

"Valid" just means that the conclusion follows from the premises. The conclusion might be false if a premise is false.

Here's an example of a valid argument with a false conclusion:

    All logicians are millionaires. (False!)
    Gensler is a logician.
    So Gensler is a millionaire. (False!)
