Hallo is the correct way of saying hello in german
Tendrías cinco años, porque está diciendo si hubieras NACIDO lo que significaría que es en ese momento hace cinco años. Espero y te ayude en mi punto de vista es algo así :)
Hi Klingelbaugh
Answer choice B) or the second option: Du schimmst nicht gerne is the correct sentence because in English that means You don't like to swim and all the other options are all the same translation and they mean you do not like swimming, so therefore B) is the correct answer because its well punctuated and sounds right.
