As i understand it, "Llevar" is more like "to carry"--when you bring items or wear clothes that travel with you because they are on you.
"At the hotel" usually refers to location so you use "en el hotel".
For comparison, there are two ways to write "I threw water balloons at the hotel." 1. You could throw water balloons at the hotel because you don't like their service. This "at the hotel" describes direction/trajectory so you use "al hotel". 2. But if you're "at the hotel" in a suite throwing water balloons at a friend, you would use "en el hotel".
At the hotel=en el hotel
" To" es la preposición de movimiento o dirección más común.
Significado: a, hacia, dirección a (siempre indica movimiento)
Uso: Se utiliza "to " para mostrar movimiento en una dirección específica
I disagree that silly sentences should be eliminated. I think one of the strengths of DL is forcing you to translate something you've never seen before, even if it sounds silly. Otherwise your translations will just be repeating something you saw before by rote, which is the weakness of many traditional language instruction systems.
Sorry to keep saying years ago when I studied Spanish but I did study it years ago and then the la pluma was a pen. It was probably the first sentence I learned in French, too, and the only one I remember: La plume de ma tante est sur la table. Boligrafo sounds like a very old fashioned word to me, but I am probably thinking of Rapidograph.
The hints are not tailored for the context of each question. Sometimes, "to wear" is a translation for "llevar" (I've only heard it used with "llevar puesto"). It's up to you to figure out the correct context/translation based on the information given.
Think of the hints as just a general dictionary that lists many possible translations for that word.
Or better yet, just keep a dictionary with you/use WordReference/SpanishDict to translate instead of relying on the hints.
Either way .... Feather or Pen is a correct translation y therefore we should have been marked as correct for using either word! Especially as they didn't give us any other context to go by for choosing one option over the other :( Not fair ... We'll just have to practice our mind reading skills more :)p!
