Two things rising together does not mean one causes the other. Hot weather leads to more ice cream sales and more swimming.
The first statement goes one way only. Many even numbers, such as 10, are not divisible by 4.
Not having proof that something is false does not make it true.
Fuel is a main cost of moving goods and people, so transport costs rise when fuel becomes dearer.
