What is the difference between effets and efforts and why is sembler cited as the "best" answer but the final para uses paraître?

Both si and tellement are used for so.  Are thee interchangeable or is there a preferred context for use?

More and more the Kwizik algorithm resembles a policeman hiding behind a bush in order to catch a speeding motorist. Please inform us if we haven't answered a question. A lot of the time it is accidental!???????????????

I still don't understand why "les" is the answer but not "ses". Please explain, thanks!

In the last sentence I typed "quand ils partent de mon salon !" but "partent de" marked as an error and advised "quittent" or "sortent de". 

Could you please explain why "partent de" cannot be used here as an option ?

For "partir", in the relevant lesson, it is written as: "When used with a place, it will always be followed by a preposition (e.g. I leave from / for  = Je pars de / pour)" Example: Je pars de cette ville.

I would like to know what the " l' " refers to in this sentence:   

Seriez-vous partis si je vous l'avais demandé? 

Would you have left if I had asked you?        

I can only surmise that it means something like: 

Why il y a du soleil and not il fait beau ?

The Collins dictionary provides the expression 'difficile à fair' and in the randomly generated examples of 'difficile' gives difficile d'atteindre; difficile à réaliser. difficile à modéliser. Is there a rule as to when 'difficile' is followed by 'de' OR 'à' and does this apply to other adjectives such as in the expression 'dur de choisir' which is given as an alternative answer in the exercise. 

I'm sure there is a lesson on this but my mind seems to have gone blank regarding it. Thanks in advance.

Which is correct? 

Je me suis réveillée tard aujourd'hui      ou

Je me suis réveillée en retard aujourd'hui ?

Please explain.
