Read the following article and select the best answer. Article: China has announced it's abolishing its one-child policy. What difference has it made, statistically speaking? 400 million births prevented The one-child policy, officially in place since 1979, has prevented 400 million births. Parents have faced fines and other punishments for having more children. The majority of the decrease in China's fertility rate happened in the 1970s. It dropped from 5.8 children per woman in 1970 to 2.7 in 1978. Despite the one-child policy the rate had only fallen to 1.7 by 2013. 21:28-baby deaths rate Since the one-child policy was introduced, baby girls have become more likely to die than boys. In the 1970s, according to the United Nations, 60 males per 1, 000 live births died under the age of one. For girls the figure was 53. In the 1980s, after the one-child policy became official, the rate for both was 36. By the 1990s, 26 males per 1,000 live births died before the age of one - and 33 girls. The 2000s saw 21 boys per 1,000 live births dying and 28 girls. 1.16 boys born for every girl Sexually selective abortions have been considered as a major cause of China's unusual imbalance. Gietel-Basten, associate professor in social policy at Oxford University, says the births of many girls are not registered if parents have broken the rule by having two children, adding officials often turn a blind eye. It's estimated there are now 33 million more men than women in China. 4: 2: 1 families With the ageing of China's population and the continuation of the one-child policy, a "4: 2 :1" home is the description given to households in which there are four grandparent, cared for by two working age parents, who themselves have one child. By 2050, it's predicted that a quarter of China's population will be 65 or older. The predicted decline in the number of people of working age is thought to have persuaded the government to drop the one-child policy. Question: When was the baby deaths rate for both boys and girls equal? - In the 1970s. - In the 1980s. - In the 1990s. - In the 2000s
In the 1980s.

Read the following article and select the best answer. Article: My parents lived through the Great Depression of the 1930s and I heard stories from both of them about how their lives changed because of it. The same was true of my in-laws whose lives were also affected negatively. For example, my husband's grandfather owned a factory. Owing to the stock market crash, he lost the factory and went back to work in the very factory he'd once owned. He could no longer afford to send my father-in-law to college. My father-in-law worked full time as a pipe fitter and went to school part-time to earn his degree, which took seven years. Somehow, my husband and I never dreamed that we would live through anything similar. However, as they say, history often repeats itself. In 1929, the stock market crashed in the month of October. The same thing happened in 2008. My husband, who had invested all our money in the market, was in a state of shock. Each day the news was more terrible. "We've lost more than half of our wealth," he told me. I just stared at him. "How can that be?" "I thought we had good, solid investments, but it seems I was wrong." "Well, we do have pensions ," I said. "Hopefully, they won't be affected. Since we have never lived a high lifestyle to begin with, I don't think we have to worry." "I did hope to leave our children and grandchildren a generous inheritance ," my husband said. He shook his head in disbelief. "We'll still be able to give gifts. Love is the most important gift anyway." Our children are grown and we always try to be generous to them and our grandchildren. "It just won't be the same." "The world is always changing," I said. "You never know what will happen. The main thing is not to get discouraged. As long as we have our health and can afford the necessities of life, there's no reason to be upset. When you have your health, you can always earn more money." I hugged my husband and he kissed me in return. "I guess you're right," he agreed. "We love each other. We have our health and enough money to live on comfortably. That's all that...

Ques: Read the following article and select the best answer. Article: Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals that are difficult to track on a day-to-day basis. However, now it seems that smart. seals have caught on to the trick and are using it to their advantage to catch fish! To find out if that is true, a team of researchers from the University of St. Andrews in Scotland selected a group often young grey seals that had neither encountered the ocean nor been exposed to any kind of acoustic tags. The researchers then placed the seals one at a time, inside a pool that contained 20 foraging boxes, only two of which housed fish -- one with tags and the other without. Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster. To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes -- one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals. While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature's food chain, the "dinner bell" effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to come up with another way to conduct their studies -- one that is not detectable by the crafty marine animals. Question: The researchers seem to believe that sharks tagged by scientists _ . - may benefit from the tags - may attract seals by mistake - may find it hard to find prey - may be annoyed by the emitted pings
Ans:
may find it hard to find prey
