Read the following passage and mark the letter A, B, C, or D to indicate the correct
answer to each of the following questions.
Long ago prehistoric man began to domesticate a number of wild plants and animals for
his own use. This not only provided more abundant food but also allowed more people to
live on a smaller plot of ground. We tend to forget that all of our present-day pets,
livestock, and food plants were taken from the wild and developed into the forms we
know today.
As centuries passed and human cultures evolved and blossomed, humans began to
organise their knowledge of nature into the broad field of natural history. One aspect of
early natural history concerned the use of plants for drugs and medicine. The early
herbalists sometimes overworked their imaginations in this respect. For example, it was
widely believed that a plant or part of a plant that resembles an internal organ would cure
ailments of that organ. Thus, an extract made from a heart-shaped leaf might be
prescribed for a person suffering from heart problems.
Nevertheless, the overall contributions of these early observers provided the rudiments of
our present knowledge of drugs and their uses.
