Question

Can you please tell me if I used the words correctly? Thank you.
I have problems defining the words in point 3.

1) Do you use a box of detergent to wash clothes in the washing machine?

2) Do you use a dish-washing liquid to do the washing-up?
3) How would you define "eco clothing"?
What is a solar-powered mobile charger?
What is a wind-up radio?
4) I think the wallet is much more practical. Great, that's sorted then (can you help me rephrase "sorted"?). I hope he likes it. (shouldn't it be "I hope he'll like it"?)

Answer 1

1 - 2 = OK

3) How would you define "eco clothing"?
(I don't know what this means -- clothing that is ecologically responsible?? Makes no sense to me!)

What is a wind-up radio?

(These are usually set up to work on 3 or 4 power sources: electricity; batteries; solar power; wind-up mechanism.)

4) I think the wallet is much more practical. Great, that's decided then. I hope he likes it. (It can be either "likes" or "will like" -- both imply something in the future, believe it or not!)
