One of the quiz questions was

The citizens choose a new president for the country.

Los cuidadanos _____ nuevo presidente para el pais.

The hint was conjugate elegir in el presente.

To make the sentence complete I typed "eligen un" for the blank, but my answer was wrong. It said the answer was "eligen". Some of the quiz questions require you to type 2 words (or more). How was I supposed to know that this specific question only wanted 1 word, which doesn't seem complete?

I was marked wrong for answering "Nosotros LES damos juguetes a nuestros hijos" instead of just "damos" I thought that the indirect object pronoun HAD to be used. What am I missing? When should I be using it? 

Thanks.

One of the examples sentences is:

 Me alegro de que hayas viajado a diferentes países.

Is the “de” obligatory  or may  it be omitted?

ie,  “Me alegro que hayas...”

How do we know if a noun is masculine or feminine in Spanish if it a new word to us?  Is there a clue I am missing or is it just a guess?

Why is the answer to " When she opens her present, she often gets perfume.

Why is the answer "abre" and not " abra"?   

I don't understand the difference between hace  and hay when talking about the weather.   Can anyone explain the difference to me?

All the examples use “no más que”. Can the title be changed to “using no más que”?

I put argentina nacional instead of nacional argentina. Can't the adjective go after the noun here or does it have to be before it? Thanks.

Where does “eso” fit in, and could it be used in the example below? If so, how would they be different?

 I think I always use “eso” in these cases; never esto. Wondering if I’ve always been wrong.

“ Esto no es lo que yo dije.
