Hello!
I believe a gerund is a "ing" word taking place as a noun. We can't be 100% sure, because it is not used in a sentence, it depends on how you use it in the sentence if it is a gerund or not. Overall, the word "writing" is not a gerund.
Hope this helps! ☺♥
A. It is the only answer that makes sense
B. late is the answer you should put in
A commonplace assertion is a statement that people just assume is correct and applies to everyone, even though there may not be any proof to support that assertion.
For example: <em>An apple a day keeps the doctor away. </em>
This asserts that if you eat an apple every day you won't ever get sick, and that is certainly not true.
