I thought that 'le présent' is used for the present and near future tenses, so why the answer of "Anne et Antoine se promènent avec leur chien." is only makert right to "Anne and Antoine are going for a walk with their dog." ?

Can't "Anne and Antoine are walking their dog." be correct as well?

I know that the question is related to the lesson but I wan't to know if that meaning is correct in the day-to-day use.

"Halloween" est une fete americaine (meme si certains commencent a` l'adopter dans des endroits comme Paris ou` bcp d'americains vivent.  Ca serait interessant de citer les fetes traditionnelles d'automne en France/ses regions ou les fetes dans des pays francophones, n'est-ce pas?  Merci.

Please help me "amis fumeurs", is that a compound noun like le service client, etc, help me explain it. Can I use "des amis qui fument (friends who smoke), somehow, it's similar to smoker friends, right?

Are there any other times apart from the negative (saying you don’t have any), when de is used eg d’huile, de pan. I know we say de also before plural nouns with an adjectives preceding the noun 

In the example 1 x 2 = 2,  the translation given is « une fois deux égal deux. » I translate this as « one times two equals two. » Why is « une » used instead of « un» ?  In contrast, I see that an another possible translation is « un multiplié par deux. »
