I don’t see the “imperfecto” conjugation available in the drop down list….what is the correct answer!

I am curious about a couple of things in the phrase below:

no podíamos quitar carga a la bicicleta.

1) Why isn't there a la in front of carga?

2) How do I decide that a is the correct proposition to use for "from the bicycle"?  My first thought was to use de.  My second thought that the English wording " remove the resistance on the bike" hinted at en.  After seeing the answer, I considered the possibility that cargar may always be followed by a (by grammar rule).

Thanks for any help you can provide.

Maybe just worth pointing out that in the sentences with "a" the preposition is used in two different ways: 

- as a "normal" preposition, for example, indicating motion: "El partido al que fui" 

- as a "personal a", where there is a direct object (Los cantantes a los que los fans adulaban) but where "a" is needed because the object is personal.

I think that's so, isn't it?

In the question "Nosotros comemos a las dos en punto  ...", using generally as the adverb, is the answer generamente or generalmente? 

One of the quiz examples translates  They achieved the objectives for the year.  using el preterito indefinido.    

My first thought would be that this sentence would fall under the "in the same time period" rule and end up being el preterito perfecto (rule is at this link) link  When to use the perfect tense versus the simple past (Perfecto vs Indefinido)

I am curious how I can tell (other than the hint given in the exercise) that this should be indefinido.

Thanks.

Could it ever be correct to say "Compré un nuevo ordenador nuevo" to express that it was both new to me and brand new? If not, how would you express that. This can be confusing in English as well.
