"He has some pens."
Translation:Él tiene algunos bolígrafos.
Something is strange here:
I gave the wrong answer and got as the correct one:
Él tiene unos esferos..
But esfero is only used in Colombia and Ecuador, the more common word is bolígrafo. Bolígrafo is also used in the title of this discussion page, so why does Duolingo show me this other word while doing the exercise?
