I need to represent these 2 arguments in standard form, but I am not sure what the conclusions are.  



For the first one, I am thinking the conclusion should be "Only if Mary shows will he attend."
The second one seems confusing to me.


Some help would be nice.

Thank you!

for the 2nd one, i think the conclusion is after "There you have it:"

Hmm...
For the second one, I think the conclusion is
no energy policy OR no tax relief.

I wonder what are the answers for both questions.. Thinking about this makes my head hurts...

I think the second is 'Election-year politicking is enough to make one cry'

Any philosophy majors or minors on LYK?

I need help with some PD and PDE claims.

Here are 2 examples that I need to prove.



These are some of the easier ones but I think some help would be great.

Thanks!

holy... i have seen these in my CMPT course.... but i don't remember what all these symbols mean now...
can you start simplifying them?

I have solved them already (took me till 5am that night).

The symbols in the 2 claims above include existential quantifier, conditional, universal quantifier, conjunction, and negation.
