The statement equivalently written in the form "if a ... then b " is which of the following?

C. If the sun is not shining, then you can ride your bike.
Solution
Solution Steps
Step 1: Understand the Original Statement
The original statement is: "You can ride your bike only if the sun is shining." This implies that riding your bike is contingent upon the sun shining.
Step 2: Convert to "If a... then b" Form
The phrase "only if" indicates a necessary condition. Therefore, the statement "You can ride your bike only if the sun is shining" can be rewritten in the form "if a... then b" as: "If you can ride your bike, then the sun is shining."
Step 3: Match with the Given Options
Now, we need to match our converted statement with the given options:
A. If you can ride your bike, then the sun is shining.
B. If the sun is shining, then you can ride your bike.
C. If the sun is not shining, then you can ride your bike.
The correct match is option A.
Final Answer
\(\boxed{\text{A. If you can ride your bike, then the sun is shining.}}\)
