Question 3 of 11

Lawn bowls (or lawn bowling balls) were originally made from a type of wood known as:

... The trees that produce lignum vitae, also called guaiacan, have become increasingly rare and, consequently, these species are considered potentially endangered. So lawn bowl manufacturers today forgo this diminishing resource and usually use melamine instead.

Question 4 of 11

A London taxi will not necessarily have:

... Although the classic London taxi is usually thought of as being black, not all London cabs sport the trademark color. But taxi specifications mandate things like the flat floor, the high roof and the tight turning radius (for making U-turns).

Question 6 of 11

The lashings, or ties wrapped around various parts of a dogsled (sometimes more than 20 on one sled), were traditionally made from moose hide, but today they are made from:

Question 11 of 11

The most important step in making carabiners for rock climbing is:
