Throughout the world there are different ways for people to greet each other. In much of the world, a handshake is the (28) _form of welcoming and greeting someone. In many countries around the Mediterranean Sea a (29)kiss on the cheek is the appropriate way to welcome friends and family. It can be a very (30)surprise if you expect to shake hands and get a kiss or a hug instead.
At times, it is difficult to tell what sort of greeting (31)is followed. People may bow, grab another‟s arm or even slap the other person on the back. In some places people just smile, look at the other‟s face and say nothing.
Most people in the world are tolerant of visitors and don‟t mind what travellers do that seems wrong
as long as the visitors are (32). A big part of the delightfulness of world travel is experiencing different customs.

6: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer for each of the questions
Humans have struggled against weeds since the beginnings of agriculture. Marringour gardens is
one of the milder effects of weeds – any plants that thrive where they are unwanted. They clog waterways, destroy wildlife habitats, and impede farming. Their spread eliminates grazing areas and
accounts for one-third of all crop loss. They compete for sunlight, nutrients, and water with useful plants.
The global need for weed control had been answered mainly by the chemical industry. Its herbicides are effective and sometimes necessary, but some pose serious problems, particularly if misused. Toxic compounds threaten animal and public health when they accumulate in food plants, groundwater, and drinking water. They also harm workers who apply them.
In recent years, the chemical industry has introduced several herbicides that are more ecologically sound. Yet new chemicals alone cannot solve the world‟s weed problems. Hence, scientists are exploring the innate weed-killing powers of living organisms, primarily insects and microorganisms. The biological agents now in use are environmentally benign and are harmless to humans. They can be chosen for their ability to attack selected targets and leave crops and other plants untouched. In contrast, some of the most effective chemicals kill virtually all the plants they come in contact with, sparing only those that are naturally resistant or have been genetically modified for resistance. Furthermore, a number of biological agents can be administered only once, after which no added applications are needed. Chemicals typically must be used several times per growing season.
With what topic does this passage primarily deal?
The dangers of toxic chemicals.
A proposal to ban the use of all herbicides.
The importance of the chemical industry.
Advantages of biological agents over chemical ones.
