It should be "esos" because 1. "Otros"and "blancos" are masculine. (Match subject's gender) 2. Here is a trick: "this" and "these" have "t"s (esto, esta, estos, estas); "that" and "those" don't (eso, esa, esos, esas). 3. "Zapatos" is plural, so match the subject's number. 4. Remember to always match the subject's gender and number. Hope that helps!
Lampara that mean lamp :)
