Answer:
The correct sentences are: "Unwanted clothing dumped in the bin ends up along with the rest of your rubbish", "Most charities have shops in your local high street", and "Clothes that are too worn to be sold can be shredded and reprocessed into new items".
Step-by-step explanation:
All these three sentences are factual because they use real life arguments and examples. Besides that, all these sentences are made up of clear statements about clothing. The first one is related to the process of how clothes end up as trash, the second is about common charities' shops around neighborhoods, and the third is about the fact that some clothes should not be discarded, but recycled.
