I see that some verbs that take de or à and the infinitive drop the preposition when an object follows the verb.  As an example, choisir de drops the preposition when referring to an object as follows:

Je choisis de partir

Je choisis la cérise

As opposed to rêver that keeps its preposition in both cases:

Je rêve de partir

Je rêve du paradis

Is there a rule for this?

Why does verb "faiblissent" agree with "bougies" and not "la lumière?   La lumière des bougies"?

The question was: "Are we waiting for Laura? No, we're not waiting for her any longer.

I put:  Nous attendons Laura? Non, nous ne l'attendons plus.

This was marked incorrect. Please explain why the pronoun "la" can't be used here, in abbreviated form with an apostrophe. 

The lesson that accompanies the question does not deal with pronouns. 

I can't see why my answer is wrong.

Please advise.

In the example, "Elle n'est pas stupide du tout!", "stupide" is used as an adjective.

However, the formulation given above says: ne + conjugated verb + pas du tout + (infinitive)

Can someone clarify this please. 

He quit smoking for five months but when the sun returned he started going out again?  Is “when the sun returned” an expression meaning when warm weather returned?
