Answer:
two pairs of friends are separated by distance & one person from each will likely create a new friendship
Step-by-step explanation:
From the story two pairs of friends have been separated by distance. One pair has Jonathan who moved from his best friend Chris. The other pair has Mr Browning whose friend Walter has moved away from.
It is likely that Jonathan and Mr Browning would create a new friendship. They both miss their old friends and seem to be lonely without them. Amongst the four, these two now live close by and are now playing chess together which could cause a new friendship to form and create a new pair.
