What the best way to say "I will not go" in French

In a recent test question: "In 1515, Francis I won the battle of Marignano." the correct answer was "a gagné" and not "gagne".  Why does the "Historical Present" not apply in this case ?https://kwiziq.learnfrenchwithalexa.com/questions/view/using-the-present-tense-like-the-past

Why can’t I say “Je le trouve grossier/irrespectueux?” As the sentence read “I find it disrespectful?”

When I take the quizzes, the answers I choose aren't the ones showing when I get the review.  It seems the quiz is changing my answers.  Is anyone else experiencing this?

In the last section covering: Il manque [quelque chose] à [qulequ’un/quelque chose/] there are two sentences that do not make use of “à”. The last one, in particular, has me stumped: “Il va manquer une chaise pour ton oncle.” What rule is this following? The impersonal examples below don’t seem to explain it. 

There seem to be too many concepts under a single heading that don’t appear to apply to them all.

In another example, given below you say that "en" is correct for a similar case

La liberté d'expression est un droit fondamental mais il faut ________ respecter les limites.

I would have thought the pastry would have been called "le gâteau" not "le biscuit" --the former is a cake, the latter is a cookie, and a bûche is a kind of cake.  Also, do some recipes for la bûche call for spreading ganache inside?  I have only read recipes that call for a whipped cream sort of filling, saving the ganache for the exterior.  I'm about the make my annual bûche de Noël and wish it were as simple as this version!

Je pense que j'entends "Je prendrai un avion..." au lieu de "Je prendrai l'avion...".  Qu'est-ce vous entendez  ?

Regarding the question ?How could you say "You need a new bike." ??

I think "devoir" would be acceptable as I perceived the possibility the person used the bike as a necessary form of transportation and the bike was either to broken to repair or was used for work.  In that case they would really need to replace the bike making devoir acceptable.

Or maybe I'm just reading too much into the questionÉ

Just to be sure. Negation also requires masculine form, am I right ?
