問4の⑤の計算はどうすれば合うのですか。 教えてください🙇‍♀️ 3枚目が答えです。

次の英文を読んで,下の設問に答えなさい。 Last year, 4.2 million babies died. That is the most recent number reported by UNICEF of deaths before the age of one, worldwide. We often see lonely and emotionally charged numbers like this in the news or in the materials of activist groups or organizations. They produce a reaction. Who can even imagine 4.2 million dead babies? It is so terrible, and even worse when we know that almost all died from easily preventable diseases. And how can anyone argue that 4.2 million is anything other than a huge number? You might think that nobody would even try to argue (that, but you would be wrong. That is exactly why I mentioned this number. Because it is not huge: it is beautifully small. If we even start to think about how tragic each of these deaths is for the parents who had waited for their newborn to smile, and walk, and play, and instead had to bury their baby, then this number could keep us crying for a long time. But who would be helped by these tears? Instead let's think clearly about human suffering. The number 4.2 million is for 2016. The year before, the number was 4.4 million. The year before that, it was 4.5 million. Back in 1950, it was 14.4 million. That's almost 10 million more dead babies per year, compared with today. Suddenly this terrible number starts to look smaller. In fact (2)the number has never been lower. Of course, I am the first person to wish the number was even lower and falling even faster. But to know how to act, and how to prioritize resources, nothing can be more important than doing the cool-headed math and realizing what works and what doesn't. And this is clear: more and more deaths are being prevented. comparing the numbers. (3). We would never realize that without

moving from " (1) 点) There are historians and others who would like to make a neat division between "historical facts" and "values." The trouble is that values even enter into deciding what count as facts-there is a big leap involved in 'raw data" to a judgement of fact. More important, one finds that the more complex and multi-levelled the history is, and the more important the issues it raises for today, the less it is possible to sustain a fact-value division. But this by no means implies that there has simply to be a conflict of prejudices and biases, as the data are manipulated to suit one worldview or another. What it does mean is that the self of the historian is an important factor. The historian is shaped by experiences, contexts, norms, values, and beliefs. When dealing with history, especially the sort of history that is of most significance in philosophy, that shaping is bound to be relevant. As far as possible it needs to be articulated and open to discussion. The best historians are well aware of this. They are alert to many dimensions of bias and to the endless (and therefore endlessly discussable) significance of their own horizons and presuppositions. A great deal can of course be learned from those who do not share our presuppositions. Our capacity to make wise, well-supported judgements in matters of historical fact and significance can only be formed over years of discussion with others, many of whom have very different horizons from our own. It is possible to I have a 12-year-old chess champion or mathematical or musical genius, but it is unimaginable that the world's greatest expert on Socrates could be that age.
