Read the passage below and answer the questions that follow.
Modern science: A double-edged sword?
The human genome map is complete. This was the startling and fascinating news with which international scientists greeted the 21st Century. It meant that they had discovered and recorded every detail about the patterns of genes in our DNA. DNA is the substance of life in the cells of our bodies, and genes are the patterns in which this substance is arranged. These patterns determine everything about our existence, from what we look like to how long we will live. Thus a full understanding of how these genetic patterns work was a very important scientific discovery for humankind.
Genetic mapping, however, was only one in a long series of scientific discoveries which have drastically changed our world and our lives over the past one hundred-odd years. These discoveries include internal combustion, aerodynamics, wireless communication and nuclear fission. Internal combustion means the production of heat energy by burning fuel inside a closed chamber. Its discovery led to the manufacture of engines which move most vehicles today. It is easy to see that modern transport would be unimaginable without such machines.
Still thinking of transport, the fastest and most efficient form of long-distance travel today is air travel. People had always dreamt of being able to fly but only a proper mastery of the principles of aerodynamics – how objects stand and move within the atmosphere – made it possible to make flying machines. Today, aeroplanes fly to and from every corner of the world. The speeds at which aircraft move is also a wonder. When the supersonic concorde jet was used for air travel, one could have had breakfast in Nairobi, lunch in London and dinner in New York, across three continents, all on the same day. This is the power of modern science.
Being able to send messages through space around the globe is another wonder of modern science. It was only in stories of fantasy that people could see and hear things many miles away. Today, this is reality, thanks to our scientific understanding of the behaviour of sound and vision waves. This understanding has lead to the invention of instruments such as the radio, television, computer and mobile phone. Today, one can watch events on a television set as they happen in any continent or even in space. Science seems to have overtaken magic.
A scientific development which is as frightening as it is fascinating is nuclear fission. Somewhere during the 1930s’ scientist found out that they could produce a tremendous amount of heat energy by splitting the cores of atoms, some of the smallest units of which
matter is made. The heat produced by splitting these atoms was so great that it could burn a whole city to ashes in a matter of minutes. Indeed, this is what sadly happened in Japan in 1945 during the Second World War. In order to win the war quickly, the Americans dropped two atomic bombs, made by nuclear fission, on two Japanese cities, Hiroshima and Nagasaki. The two cities were destroyed instantly and thousands of people were killed. The Japanese were so shocked that they surrendered immediately. Science had helped the Americans to win the war, but at what cost!
This brings us to a very important point about science. It has both benefits and dangers. Our understanding, control and use of nature, which is what science is, can be used for good or for evil, Mastery of human genome, for example, can help in the control of hereditary diseases. A clever rearrangement of a person’s genes may prevent them from inheriting breathing problems characteristic of asthma or uncontrollable bleeding caused by haemophilia. This would be science in the service of humankind. On the other hand, an evil scientist may manipulate human genes to create monsters. Scientist have managed to clone animals such as cattle, sheep and rabbits. A clone is an animal that is an exact genetic copy of another animal. Some scientists have even contemplated producing cloned human beings! What kind of human beings these will turn out to be; only time will tell.
Questions:
1. How did scientists greet the 21st century?
2. Name four scientific discoveries that have been made in the last one hundred years?
3. What according to the passage demonstrates the advantages of aerodynamics?
4. Mention one scientific discovery which is said to have overtaken magic.
5. Explain how an atomic bomb is made.
6. Why did the Americans drop atomic bombs in Hiroshima and Nagasaki?
7. How can scientific discoveries in the area of genetics benefit humankind?
8. What is the possible danger of the discoveries in genetic research?
9. Comment on the relevance of the title of the passage.

Read the comprehension below and answer the questions that follow.
Prof Atieno Ndede-Amadi the head of the university’s school of Business at Technical University of Kenya (TUK) and associate professor of information systems and accounting, has embarked on a crusade to convince her peers of the need to introduce information systems (IS) analysis as a complete academic programme. She believes that the course would benefit young people interested in IT, as well as local enterprises that have had to rely on expatriates with the skill.
Prof Atieno’s concern arises from her own study. She established that despite a high demand for information system analysts there weren’t many Kenyans specially trained for the job.
As such, companies were hiring outsiders as local universities continued to concentrate on broad range computer science and programming courses, and failing to give much thought to IS analysis.
Information system analysts are trained to evaluate and develop technology systems to help business to run optimally. They identify user and consumer needs and translate them into technology solutions. Despite this critical function, there aren’t many people called IS analysts in the local market, and that’s because the universities here have not been keen to train in this specialization.
“A wide systems analysis skills gap exists in the country due to the absence of strong information system academic programs in local universities.” Prof Atieno states in her study report which is titled,” Information Systems Education in Kenya: Students Specialization Choice trends.” The work has been published in the International Journal of Education and Development using Information and communication Technology (IJEDICT). The study found that of all the 32 public universities and university colleges studied, none offered an information systems or management information systems degree. Only two degrees came close with four institutions offering a Bachelor of Technology (Business Information Technology) degree in varying combinations, and one university offering a Bachelor in Business Information and Management.
Prof Atieno says that if both students and university heads fully appreciated the value of information systems analysis, they would be more focused on it as an area of study. She actually established in her study that the supply gap of people with the skill is largely a result of ignorance. Globally, a majority of IS programs within universities are located in business schools, and they have names such an information systems, management information systems, computer information systems, business information systems, or business information technology. An IS degree programme combines business and computing topics, with the emphasis on technical and organizational issues varying from one programme to another, and also from one academic institution to the next. Generally, it bridges business and computer science, using the theoretical foundations of information and computation to study various business models and related algorithmic process within the computer science discipline.
According to Prof Atieno, organizations cannot effectively and efficiently do business without solid IS setups for connecting systems within as well as with its supply chain stake holders, such as vendors and distributors. Yet, many students aren’t aware of the possibility of a career in this field. In fact, the study found that only 11% of those interviewed knew about IS analysis as a possible area of specialization. “An Information system as an academic discipline seems to be largely unknown to high school students in Kenya, making it impossible for them to select it as an area of specialization in their university education,” it states. The net effect is that the level of IS education in the country has suffered, resulting in a deficiency in systems analysis and related skills.

Read the passage below and answer the questions that follow.
WASTE DISPOSAL
Population in most cities increasing at a very high rate. The high population results in high levels of activities and consumption. People in cities consume a lot of food and they buy groceries from shops, which are wrapped in polythene bags. As a result, a lot of garbage is generated and disposed off within and outside the urban areas. The higher the population, the higher the amount of garbage generated. This means that there should be an efficient system of collecting and disposing off the garbage.
The effectiveness of waste management by city councils varies from country to country. In most African cities, a large amount of waste is not deposited in rubbish pits. Instead, it is dumped in the open. According to United Nations Environmental Program (UNEP) statistics, sixty five percent of garbage in Tripoli, for example, is dumped in the open while eighty percent of garbage in Ismailia (Egypt is also dumped in the open.
With extreme warm temperatures such garbage tends to decompose rapidly causing serious health risks besides being a nuisance. One common method of deposing off waste is open burning. This contributes to the problem of urban air pollution.
In Nairobi, for example, it is common to find informal open burning sites. Most residents of city estates say that they are forced to burn waste in the open because the city council is incapable of dealing with the increasing amount of garbage. When waste is not disposed off effectively, it affects human health and damages the environment. For example, it has led to problems such as pollution of water sources, offensive odour, and increase in disease vectors, pests and scavengers.
However, there are examples of domestic waste being disposed off hygienically or being recycled. For example, in rural Egypt, there are organizations that promote environmental awareness among women by providing them with plastic bags so that they can collect their garbage. On the other hand, the youth are given the task of taking the garbage to a designated collection point. This scheme can be imported to the urban areas with a lot of success.
Another possible solution could be the introduction of reusable shopping bags in place of the usual polythene bags. Supermarkets and other businesses can pack customers’ goods in bags that are reusable. This would drastically reduce the amount of domestic waste generated everyday.
Questions
a) What is the result of high population in most cities?
b)In most African cities, where are large amounts of waste deposited?
c)How much waste does Egypt dump in the open?
d)What two problems result from dumping waste in the open?
