Read the following passage and select the best answer for each of the questions that follow. Analyzing the physics of dance can add fundamentally to a dancer's skill. Although dancers see themselves totally in physical terms as body mass moving through space under the influence of well- known forces and obeying physical laws - neither can they afford to ignore the physics of movement. For example, no matter how much a dancer wishes to leap off the floor and then start turning the law of conservation of angular momentum absolutely prevents such a movement. Some movements involving primarily vertical or horizontal motions of the body as a whole, in which rotations can be ignored, can be studied using simple equations of linear motions in three dimensions. However, rotational motions require more complex approaches that involve analyses of the. way the body's mass is distributed, the axes of rotation involved in different types of movement, and the sources of the forces that produce the rotational movement.The primary purpose of the passage is to -

Exactly 7 children P, Q, R, S, T, U, and V participated in and finished all of a series of races. There were no ties for any position at the finish of the races. The facts about the races were revealed as: V finished somewhere ahead of P and P finished somewhere ahead of Q. Not only that, either R finished first and T finished last, or S finishes first and U or Q finishes last. If in a race S finishes sixth and Q finishes fifth, which of the following can be true?

If x, y and z are positive integers, and 4x = 5y = 6z, then what is the least possible value of x + y + z?

Why save endangered species? For the general public, endangered species appear to be little more than biological oddities. A very different perception is gained from considering the issue of extinction in a wider context. The important point is that many major social advances have been made on the basis of life forms whose worth would never have been perceived in advance. Consider the impact of rubber-producing plants on contemporary life and industry: approximately two-thirds of the world's rubber supply come from rubber-producing plants and is made into objects as diverse as rubber washers and rubber boots. Any of the following facts could be used as illustrative examples in addition to the example of rubber-producing plants EXCEPT-

Two friends, Rajib and Rahat, entered into a partnership investing Tk. 700 and Tk. 600 respectively. After 3 months, Rajib withdrew 2/7 his investment but after 3/5 months, he reinvested 3 of what he had withdrawn. The profit at the end of the year was Tk. 726. If the profit was shared according to time weighted investment, then what was the difference between the profits of those two friends?

In a sample of 900 university students, all students are either freshmen or sophomores or junior or seniors, 24 percent are juniors and 72 percent are not sophomores. If there are 144 seniors, how many more freshmen than sophomores are there among the sample of students?

At what acute angle, in degrees, is the minute hand and the hour hand of a clock inclined at 22 minutes past 6?

There are 9 novel books, 4 drama books, 12 poetry books and 7 grammar books in my bookshelf. The books are randomly arranged in the shelf and not at all in the order of their type. My reading room where that bookshelf is located lacks sufficient lighting during evening time and as a result of that, types of that bookshelf are not visible, what is the least number of books that must be drawn from the bookshelf in the evening in order to get 6 books of a particular type?

The length of a rectangular field is four times its width. If the cost of cultivating the field at Tk. 20 per square meter is Tk. 1,280 then what is the perimeter, in meters, of the rectangular field?

In a class, the average score of boys in an examination is 64 and that of girls is 61, If the average score of the whole class is 62.2, then what percent of the class are the boys?

Which of the following represents the ratio of the volumes of two solids, namely cylinder and cone having equal base area and height?

Read the following passage and select the best answer for each of the questions of that follow.National character is not formally considered by social scientists in discussing economic and social development today. They believe that people differ, and that these difference should be taken into account somehow, but they have as yet discovered no way to include such variables in their formal models of economic and social development. The difficulty lies in the nature of the data that supposedly define different national characteristics. Anthropologists and others are on much firmer ground when they attempt to describe the cultural norms for a small homogeneous tribe or village than when they undertake the formidable task of discovering the norms that exist in a complex modern nation-state composed of many disparate groups. The situation is further complicated by the nature of judgments about characters since such judgments are overly dependent on impressions, and since, furthermore, impressions are usually stated in qualitative terms, it is impossible to make a reliable comparison between the national characters of two countries.It can be inferred from the passage that the social scientists mentioned in lines 1-4 would agree with which of the following statements?I. It is extremely difficult to create models that account for both economic and social development.II. Models of economic and social development would be improved by the inclusion of adequate descriptions of national character.III. It is important to supplement formal models of economic and social development with qualitative impressions of national character.
