Question

HELP —¿Qué piensas de estas botas? —_____ que cuestan demasiado.
A. Piensan

B. Pienso

C. Pensamos

D. Piensas

Answer 1

Pensar- it means "to think"
This is a weird verb, so when you conjugate it to the "present-tense" you are going to the the "e" in Pensar, to "ie". Like pienso, piensas. etc. The only time you don't change is is for the nosotros, and vosotros. My old spanish teacher told us to think of it like a boot. Everything inside the boot is changed and the ones outside are not.
