The right answer is B. You have to look at the whole sentence to understand this. Look back to the beginning of the verb phrase: "The Penniworths were forced to...." The verbs following this construction need to be in the base form ( e.g. 'sell') If you read the whole sentence, you'll see that they were forced to do two things: 1. ..........sell their spacious brownstone overlooking the park" 2. ......... move into a small apartment on the outskirts of the city" Both of these actions follow on from the construction 'were forced to...' I hope that makes sense.

Hi Zahedi You are almost correct. You must use 'and' in order to link the two parts of sentence together. Once you have linked the sentences then the idea of being 'forced to' applies to both subsequent verbs - 'sell' & 'move' - and both need to be infinitives. So, number 2 is the best answer from the 4 options. If there was another answer option "and they moved" I would choose this in fact, because really although the financial problems forced them to sell you could argue that they had lots of choices of where to move to (as long as it was cheaper), but as that answer isn't an option you have to go with number 2! Hope this makes sense. Chris

I think 4 is wright.
