This Mix and Match quiz challenges you to find pairs and opposites.
'Mix and Match' is the wording on signs that you sometimes see in shops where you can pick your own items in a range of colours, flavours etc.
English has many pairs of words ~ often as synonyms or antonyms ~ and which hang well together by their sound, because they alliterate or rhyme.
How many of these do you know, or would you recognise?
Answer 2 dates from the earlier days of voice-radio communication, particularly among uniformed personnel (e.g. the armed and emergency forces): they would say 'Over' when they wanted the person at the other end of a conversation to speak, and 'Over and out' to end the conversation completely.
'Dead and buried' (Answer 3) would be tempting, but inappropriate, in these circumstances; Answer 4 may seem quite fun, but is a made-up example.
