What is the difference between a synecdoche and a metonymy?

Synecdoche refers to a thing and its parts. The best example is the use of the word “wheel” instead of “car”. As we know, a wheel is a car part. 

On the other hand, metonymy refers to a thing that is very much related to another thing. The easiest example we can use here is the word “crown” when used in some literature pieces means power.

the examples that saki used to represent satire through situational irony are options two (2) and five (5) inasmuch as the wolf thought that looking for a girl in the bushes could be as easy as hunting little pigs at the park, but it took him so much time to find the girl if it had not been not for a silly mistake. also, bertha would have survived to the wolf's hunt if she had not won those medals for goodness, which at the end they were what got her killed by making noise, so winning medals of goodness was not so good achievement, after all.
