Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42Nepal has made important progress over the past few years to promote equality, but the country still has one of the highest rates of child marriage in the world. 41% of Nepalese girls are married before the age of 18.Poverty is both a cause and consequence of child marriage in Nepal. Girls from the wealthiest families marry 2 years later than those from the poorest, who are seen as an economic burden, and who drop out of school and earn little money.Food insecurity plays an important role too. Nepalese families that do not have enough food to eat are more likely to marry their daughters at a young age to decrease the financial burden. One study shows that 91% of people who had secure access to food married over the age of 19.Dowry is also common practice in many communities. Parents marry their daughters as soon as possible because the money they have to pay to the groom’s family is higher if their daughter is older. Since 2010, the legal age of marriage is 20 for both men and women, or 18 with parental consent, according to the Nepalese Country Code.The law states that punishment for child marriage is imprisonment for up to three years and a fine of up to 10,000 rupees (£102). But reports suggest that this law is rarely applied. There has been quite a lot of progress in Nepal over the past 3 years with a clear government commitment to ending child marriage and civil society cooperation. The Ministry of Women, Children and Social Welfare is currently developing Nepal’s first national strategy on child marriage in collaboration with UNICEF Nepal and Girls Not Brides Nepal. However, the post-earthquake and post-fuel crisis environment has meant progress is slow and the national strategy has been delayed.(Adapted from http://www.girlsnotbrides.org/)It can be inferred from the passage _________

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42There are many theories of aging, but virtually all fall into the category of being hypotheses with a minimum of supporting evidence. One viewpoint is that aging occurs as the body's organ systems become less efficient. Thus failures in the immune system, hormonal system, and nervous system could all produce characteristics that we associate with aging. Following a different vein, many current researchers are looking for evidence at the cellular and sub cellular level.It has been shown that cells such as human fibroblasts (generalized tissue cells) grown in culture divide only a limited number of times and then die. (Only cancer cells seem immortal in this respect). Fibroblast cells from an embryo divide more times than those taken from an adult. Thus some researchers believe that aging occurs at the cellular level and is part of the cell's genetic makeup. Any event that disturbs the cell's genetic machinery such as mutation, damaging chemicals in the cell's environment, or loss of genetic material, could cause cells to lose their ability to divide and thus bring on aging. Other theories of aging look at different processes. Chronological aging refers to the passage of time since birth and is usually measured in years. While chronological age can be useful in estimating the average status of a large group of people, it is a poor indicator of an individual person's status because there is a tremendous amount of variation from one individual to the next in regard to the rate at which biological age changes occur. For example, on the average, aging results in people losing much of their ability to perform strenuous activities, yet some elderly individuals are excellent marathon runners.Another type of aging is cosmetic aging, which consists of changes in outward appearance with advancing age. This includes changes in the body and changes in other aspects of a person's appearance, such as the style of hair and clothing, the type of eyeglasses, and the use of a hearing aid. Like chronological aging, it is frequently used to estimate the degree to which other types of aging have occurred. However, it is an inaccurate indicator for either purpose because of variation among individuals and because a person's appearance is affected by many factors that are not part of aging, including illness, poor nutrition, and exposure to sunlight.The author implies all of the following about cosmetic aging EXCEPT________
