Question

Select the sentences in the article that are based on fact.

When talking about recycling, people don't seem to consider the recycling of clothes.
Unwanted clothing dumped in the bin ends up along with the rest of your rubbish.
It is a terrible waste not to pass on your unwanted clothing to a charity.
Most charities have shops in your local high street.
It is really easy to take your discarded clothes to be recycled.
Charities can post collection bags and make door to door collections for your unwanted items.
Watch out for unscrupulous businesses that make collections and then keep any profit for themselves.
You shouldn't just throw away your old clothes because you think they're too threadbare to resell.
Clothes that are too worn to be sold can be shredded and reprocessed into new items.

Answer 1

 I would say "Charities can post collection bags and make door to door collections for your unwanted items." and "Clothes that are too worn to be sold can be shredded and reprocessed into new items." 
 Simply because those are facts and not suggestions or opinions. There could be more than those two though. 

Answer 2

The correct answers 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.
• Charities can post collection bags and make door to door collections for your unwanted items.
• Clothes that are too worn to be sold can be shredded and reprocessed into new items.  

The sentences on the list are presented in a manner that the speaker disables the reader from arguing, which is characteristic of facts, rather than of opinions.

The rest of the options are written with a low level of certainty with the use of phrases such as "people don't seem", "It is really easy", and "You shouldn't" - which makes them accurate only from the speaker's own personal viewpoint.
