PUNCTUATION
For questions 6 to 12, choose the correct punctuation to complete the passage. Circle the best
answer.
In most large cities [6] like Singapore, we can only see a few of the large bright stars out in
space. This is due to the increased pollution of earth [7] s atmosphere especially in the cities.
The polluted skies obscure most of the other smaller stars [8] However [9] the stars are
fascinating to some people who take up astronomy as a hobby to study the stars. [10] We love
to take a close-up look at the stars [11] [12] said Jenny, as she went to the Science Centre to
use the telescopes set up for people to use free of charge.
