in this example, two questions:

Ce sont les meilleures vacances qu'elle ait passées!

1. why "ce" instead of "ces", if vacances is plural?

2. why pasées instead of passée, if the noun is singular and avoir doesn't match in number?

Hi,  my kwizbot it is telling my that in this example,”Cette maison est bien. - Oui, elle est ________ l'autre.” 

the correct answe is “mieux.” Why? Doesn’t mieux modify a verb? Here were modifying a noun (maison), so it should be “meilleur” by all logic, so why is the correct answer “mieux”? 

Could 'les infos' be substituted by ' l'actualité ' or ' nouvelle ' Thanks

Is there any way of speeding up the audio to something more akin to proper speech?

Is there a mistake in the video at approximately the 1:08 mark? The example says:

Je mange une pomme and Tu *parle* à Marie. Shouldn't it be Tu *parles* à Marie?

In example   

Why venions? Subjunctive?

The end of the passage states, "d'ici trois jours ouvrables" or "dans", but the English phrase to translate is "within" so should en not be used instead of dans? En being within and dans being similar to after ex number of days.
