Duration: 2:30 Hours

INSTRUCTIONS. 

  1. This paper consists of sections A, B, C and D with a total of ten (10) questions.
  2. Answer all questions in the spaces provided.
  3. All writing must be in blue or black ink
  4. Calculators, cellular phones and any unauthorized materials are not allowed in the examination room.

SECTION A (20 Marks)

COMPREHENSION AND SUMMARY.

1. Read the following passage carefully and answer the questions that follow.

Drugs are chemical substances that can change the way one thinks and works. People used drugs to change their feelings. The most abused drugs are marijuana or cocaine, heroin and alcohols. Drug abuse is common in almost all the developed and developing countries. Billions of dollars are spent internationally for preventing drug abuse, treating and fighting drug related crimes.

Drug abuse causes multiple problems in countries and communities. Firstly, it causes medical and psychological problems. It is obvious that addicts cannot function as normal members of the society. They neglect or abuse their families and eventually they require expensive treatment or hospitalization. In Tanzania especially in urban areas, it is common to see teenagers who are not only weak but also sick. These young men and women are so aggressive and they constantly break the law. In addition, they are extremely violent as they easily get into physical fights. These Tanzanian addicts pose a vivid example of the medical and Psychological problems faced by the addicts all over the world. 

The second problem caused by drug abuse is the increase of crimes. There some crimes which are either drug influenced or drug related. These crimes are petty or organized ones. Drug addicts are likely to involve themselves into such petty crimes as robbery, burglary and theft. They do so because they want money to buy drugs and food. It is worth noting that most drug addicts are not employed. Drug dealers can also organize themselves into criminal gangs which get money from drugs. Police and legal resources are therefore needed to fight crime related to drugs or the crimes influenced by drugs. 

However, the threat of drugs can be fought successfully if some strategies are employed. Education on drug abuse is the first way of combating the problem. People especially children need to be educated at home or in school about drugs. People need to be aware of drugs so that they can avoid using them. Also, families and counselors need to talk to children and people at risk. Parents need to take care of their children and help them to become responsible citizens. Moreover, jobs need to be created to give people sources of steady income. However, effective laws should be enacted so that the criminals can be caught and taken to the court. 

Although the problem of drug abuse may seem impossible to eliminate easily, there are concrete strategies that can be taken to weaken drug dealing in the society. The danger of drugs is too great to ignore. 

Questions:

(a) Answer the following questions with reference to the passage.

(i)     Where in Tanzania is drug abuse mostly practiced?

………………………………… ………………………………  



(ii)  Who is a drug addicted?



(iii) Why are drug addicts involved in crimes?

(iv) Explain the meaning of the expression, “Multiple problems”.

(v)   Give three ways of eliminating drug abuse.

(b) For each of the following statements, write TRUE if the statement is correct or FALSE if the statement is not correct.

(i)     Countries spend a lot of money to fight drug abuse………………

(ii)  Drug addicts are very polite……………………….

(iii) Parents have roles to play in combating drug abuse……………..

(iv) Usually people who use drugs do not break the law…………………..

(v)   The problem of drug abuse is so big that we cannot solve it…………….



2. Read the following passage then write five descriptive words used in the passage.

Wind is air in motion. The chief cause of winds is the difference in the pressure of the air. Heated air near the earth’s surface, being light, rises into the higher regions while cold air from the surrounding regions moves into this low pressure area to equalize the pressure of the atmosphere. This movement of the air is called wind. Winds blow from areas of high pressure to areas of low pressure. Winds are named by the direction from which they blow, but the deflection of the winds is due to the rotation of the earth. Winds are deflected to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere.

Answers:
