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.
