8. Before you. go (1) shopping for your mother, she makes. sure (2) that you have enough money (3) in your wallet (4). This money (5) will be in the form (6) of coins or banknotes.
It is difficult for us to realize that there are shops in some (7) parts of the world (8) where money as we know it (9), coins and notes, would be of no (10) use. In the markets and bazaars of these countries a handful of shells, a few beads, a bar of metal or some dogs' teeth might be(11) useful for buying (12) goods, but pounds (13) and pence, dollars and cents (14) would buy nothing. For the natives of the (15) Indian islands, shells are "money" as are dogs' teeth to the tribes in some of the South Sea Islands.

In parts of Africa and in (20) the native tribes of South America, and some of the more remote islands of the Pacific, selling is still mainly a matter of barter.

"'You have a very (14) strange sense of humor (15), sir."
”I knew (16) you'd laugh," said Groom angrily (17); "but let (18) me put a question to you. In (19) your opinion, which laboratory in the world is most likely (20) to have achieved this development?"
