*SENTENCE COMBINATION*

Learning to combine ideas into more complex sentences is an important writing skill. There are many ways to do this. Try to combine the following three sentences.

Sentence 1: An apartment in Hyde Park has recently been put up for sale.

Sentence 2: The asking price is more than 150 million (Canadian) dollars.
Sentence 3: It is thought to be the most expensive flat ever to go on the open market.
