Explanation:

I have been able to identify the sentences that were correctly and incorrectly punctuated.  

Commas are usually used to separate independent clauses. This happens  when commas are actually joined by any of these seven coordinating conjunctions: and, but, for, or, nor, so, yet.

Semicolon is often used when linking (in a single sentence) two independent clauses. These independent clauses are closely related in thought. While the colon for separating two independent clauses when the second sentence actually explains or illustrates the first. It's seen that the colon actually functions in the same way as the semicolon.

when making an inference, the reader should be sure to support the inference with

evidence

a is an educated guess about what will happen.

c. prediction

when new information proves that a reader's prediction is wrong, the reader should

make a new prediction based on the new information.

d understatement
