Rewriting Conditionals In Their Well Known Form The question is, 
"Write each of these statements in the form “if p, then q” in English. [Hint:Refer to the list of common ways to express conditional statements.]
a) It snows whenever the wind blows from the northeast.
b)The apple trees will bloom if it stays warm for a week.
c) That the Pistons win the championship implies that
they beat the Lakers.
d)It is necessary to walk 8 miles to get to the top of
Long’s Peak.
e) To get tenure as a professor, it is sufficient to be world-
famous.
f) If you drive more than 400 miles, you will need to buy
gasoline.
g)Your guarantee is good only if you bought your CD
player less than 90 days ago.
h)Jan will go swimming unless the water is too cold.
I am having a little trouble with c), g), and h).
For c): Presumably, it would appear that this sentence is discussing a championship match, one between the Lakers and Pistons. Hence, I am having difficulty seeing why it has to be written a particular way. Doesn't "If the Pistons win the championship, then they beat the Lakers," and "If the Pistons beat the Lakers, then they win the championship," convey the same meaning?
For g): This is another instance of me not seeing why this conditional statement has to be written any particular way. To me, "If you bought your CD player less than 90 days ago, then your guarantee is good," and "If your guarantee is good, then you bought your CD player less than 90 days ago," convey the same meaning.
For h): I wrote, "If the water is too cold, then Jan won't go swimmming;" however, the answer key says, "If the water is NOT too cold, then Jan will go swimming." Would my answer be acceptable?
 A: (c) It’s not discussing a single championship match; rather, it’s talking about the entire post-season tournament. Thus, it’s conceivable that the Pistons could beat the Lakers and later lose to some other team.
(g) It doesn’t actually say that your guarantee is good if you bought your CD player less than $90$ days ago; it just says that if you bought the CD player $90$ days ago or earlier, your guarantee definitely isn’t good. There might be other conditions. For instance, it might be no good if you drove your car over the CD player, even if you bought the CD player yesterday.
(h) No. ‘Jan will go swimming unless the water is too cold’ guarantees that if the water is not too cold, Jan will definitely go swimming. In everyday language it very strongly suggests that if the water is too cold, she won’t go swimming, but in strict logical language it does not actually say this: it could be the first half of the statement Jan will go swimming unless the water is too cold, and maybe even if it is.
A: Rearranging the expressions and highlighting "key words":


*

*c) (The Pistons win the championship) implies (they beat the Lakers). "p implies q" $\iff$ "$p \rightarrow q$" = "If p then q". 

*g) (Your guarantee is good) only if (you bought your CD player less than 90 days ago). "p only if q" $\iff$ "$p \rightarrow q$" = "If p then q".

*h) (Jan will go swimming) unless (the water is too cold.) That is: If (it is not the case that the water is too cold), then (Jan will go swimming) $\iff$ "If (the water is NOT too cold), then (Jan will go swimming).  You can think of "unless" as meaning "if not". Then we have "p unless q" $\iff$ "p, if not q" $\iff$ "if not q, then p".
