Usage of à vs de.

The lecture above says this:

Bonjour à tous!

Le substantif "science fiction" s'écrit-il avec ou sans tiret? Dans mon dictionnaire Larousse, c'est écrit avec un tiret. C'est un petit détail, mais je préfère être certain. Merci! 

In the question...

Comment ________ tes vacances ?How are your holidays going?... I wrote "vont" instead of "se passent". Why is that unacceptable, given that you can say "Comment allez-vous?"? Can you only use "aller" with people to mean "go" in this sense?

In the question...

________ retarde le train, c'est la grève.What delays the train is the strike.... I wrote "Cela qui". Why is "cela" not acceptable?

why do we say je ne veux ni chanter ni danser

but we  do say tu n'avais envie ni DE sortir ni DE voir du monde?

I found the accent of the winegrower Frédéric Berne in this video easy to understand, at least after I went into the text and read that. I looked for any pertinent information on the video at youtube, but I found no answer to my question: Do you happen to know what accent M. Berne in the video has?

I remember a lesson (https://www.lawlessfrench.com/grammar/aller-lesson/) saying that "aller" always has to have a destination indicated. (Hence allons-y! rather than allons!, etc.) Is "avec toi" enough to satisfy that rule?

(first off, the software doesn't allow an accent on the "e" in "apres" on this page... I didn't forget :-)

In doing an exercise, I got a question wrong. I think I got it wrong because I answered "jeudi suivant" instead of "le jeudi suivant" -- but the only correct answer provided was "le jeudi d'apres." However, the lesson seems to say that "le jeudi suivant" would also be correct. Should this also be provided as a possible correct answer, or what am I missing? Thanks!

I consulted Reverso for the translation of two propositions from this lesson:

1. Dinner will be served within an hour

2. Dinner will be served in an hour's time

Both produce the same french phrase: 

Le dîner sera servi dans une heure

My question: why Kwizbot showed error to my translation into English that read “Dinner will be served within an hour”
