1.Which two statements prove that Hana is younger? A. Hana lives with her brother. B. Hana is the little sister of Alemu. C. Alemu is still a student. D. Alemu has just turned 14.
- A. C and D
- B. A and C
- C. B and D
- D. B and C
Answer: C. If Alemu has just turned 14 (statement D) and Hana is his little sister (statement B), Hana must be younger than 14, proving she is younger.
2.Read the following three statements which are followed by four conclusions. Choose the conclusions which logically follow from the given Statements: crows are black. All black birds are loud. All crows are birds. Therefore 1. All birds are black 2. All crows are black 3. All birds are loud 4. All crows are loud
- A. Only (2) and (3)
- B. Only (1) and (4)
- C. Only (2) and (4)
- D. Only (3) and (4)
Answer: C. The question tests which conclusions must follow from the statements. Since all crows are black and all black birds are loud, all crows are loud; the statement also directly says all crows are black. Conclusion 1 is too broad because the statements do not say all birds are black; conclusion 3 is too broad because they do not say all birds are loud; options A, B, and D each include one of these unsupported conclusions.
3.Statements: Some questions are answers. Some answers are writers. All the writers are poets. Conclusions: 1. Some writers are answers. 2. Some poets are questions. 3. All the questions are poets. 4. Some poets are answers.
- A. Only (1) and (4)
- B. Only (1) and (2)
- C. Only (2) and (3)
- D. Only (3) and (4)
Answer: A. The key idea is to decide which conclusions must follow from the statements. Some answers are writers, so some writers are answers; those writers are poets, so some poets are answers, making conclusions 1 and 4 true. Conclusion 2 is not certain because the questions and writers may be different answers; conclusion 3 does not follow because not all questions are said to be poets.
4.Statements: Some envelops are gums. Some gums are seals. Some seals are adhesives. Conclusion 1. Some envelopes are seals. 2. Some gums are adhesives. 3. Some adhesives are seals. 4. Some adhesives are gums
- A. Only 1
- B. Only 3
- C. Only 4
- D. Only 2
Answer: B. The key is that a statement about some members of two groups can be reversed. “Some seals are adhesives” means “some adhesives are seals,” so conclusion 3 follows. Conclusion 1 does not link envelopes with seals; conclusion 2 does not link gums with adhesives; conclusion 4 is not guaranteed by the statements.
5.Mike finished ahead of Paulos. Paulos and Berhanu both finished before Lema. Orion did not finish last. Who was the last to finish?
- A. Lema
- B. Orion
- C. Paulos
- D. Berhanu
Answer: A. The question tests putting people in order using the clues. Mike finished before Paulos, and both Paulos and Berhanu finished before Lema; Orion was not last, so Lema was last. B is ruled out by the Orion clue; C and D are ruled out because both finished before Lema.

Regular physical activity provided numerous health benefits. : from leaner bodies and ,lower blood pressure to improved mental health and cognitive functioning. As the school physical education program promotes physical activity and can teach skills as well as form or change behavior, it holds an important key to influencing health and well being across life span. To improve the fitness of students, we need to rethink the design and delivery of school- based physical education program. Adults in some countries think that information about health was more important for students to learn than content in language arts, mathematics, science, history or any other subject. Despite this high ranking, most skills devote minimum curriculum time to teaching students how to lead healthy lives. Our first step might be to consider ways to increase curriculum time devoted to physical education. In addition, schools need to thoughtfully analyze the design and delivery of school physical education programs to ensure that they are engaging, developmentally appropriate, inclusive and instructionally powerful.

Marie Curie was one of the most accomplished scientists in history. Together with her husband, Pierre, she discovered radium, an element widely used for treating cancer, and studied uranium and other radioactive substances. Pierre and Marie's amicable collaboration later helped to unlock the secrets of the atom. Marie was born in 1867 in Warsaw, Poland, where her father was a professor of physics. At an early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master's degree and doctorate in physics. Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress. Curie's feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world.

Which of the following system of linear inequalities is represented by the graph given below? [Figure: A Cartesian plane with the horizontal x-axis (arrowhead at the right, labelled x) and the vertical y-axis (arrowhead at the top, labelled y). Three straight lines are drawn, all as plain solid lines with no shading of any region: (1) a line of positive slope rising left to right, crossing the x-axis at the marked point -1 and the y-axis at the marked point 1, so it passes through (-1, 0) and (0, 1); (2) a line of negative slope falling left to right, crossing the y-axis at the same point 1 and the x-axis at the marked point 1, so it passes through (0, 1) and (1, 0); the two lines cross each other on the y-axis at (0, 1). (3) a horizontal line running the full width of the drawing at the level of the marked point -1 on the y-axis, that is the line y = -1. The three lines enclose a triangle whose apex is at (0, 1) and whose base lies on y = -1. Axis marks shown and labelled: -1 and 1 on the x-axis, 1 and -1 on the y-axis.
