正解は2番なのですが、どういう理由でそうなるのかが分かりませんでした。詳しく教えてください！

21:03 の マ 自46% 294 長い文章 16 What does the speaker say about Abraham Lincoln's speech? 0 It was considered a complete failure. 2 It was given at a cemetery for soldiers. 3 It was nearly two hours long. の It was given a score of four out of seven. Sp The Gettysburg Address The Gettysburg Address is one of the most famous speeches in U.S. history, but when Abraham Lincoln finished delivering the speech, he thought it had been a complete failure. The speech was not even the main speech given that dov.a dedication of a cemetery for the thousands of soldiers who had died in the Battle of Gettysburg a few months earlier. After the main speaker had spoken for nearly . hours, the President spoke for only a few minutes. His speech was only ten senten.. long, but it reminded Americans why they had fought to create a new country and urged them to fight on to save it and make it greater. The reason Abraham Lincoln's speeches are so memorable is that he wrote and rewrote them until they sounded almost like poetry. For example, he ends the speeck with, “that government of the people, by the people, for+he people, shall not perish from the earth." By repeating, "of the people, by the people, for the people," he makes the phrase easy to remember. But, of course, it is the opening of the speech that even school children can recite: “Four score and seven years ago." A“score" is twenty years, so he is really saying, “Eighty-seven years ago.” But “eighty-seven years ago" doesn't sound very poetic, does it?

just after とはどういう意味ですか、品詞は何ですか？

和訳これで合ってますか?? お願いします❕❕

6/ Similarly, we have forty, and sixty, which sound like four, and six. We also say, however, fifty and thirty and twenty, which somewhat sound like five, three, and two respectively, but not really. Moreover, for numbers above twenty, we put the double-digit number first and the single-digit second: twenty-one, twenty-two. For the teens, though, we do it the other way around. We put the double-digit second and the single-digit first: fourteen, seventeen, eighteen. TIotom in Enaliah :

2行目なんですけど、この場合の number-naming ってなんて意味ですか??

5/It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. We English speakers say fourteen, sixteen, seventeen, eighteen, and nineteen, so you may think that we also say one-teen, two-teen, and three-teen. But we don't. We make up a different form: eleven, twelve, thirteen, and fifteen.

as long as とas far as の違いが分かりません どっちも「〜する限り」ですよね？

(5)に解答ではrefers toが〜を意味するであるからと書いてありました。accounts for も〜を説明するという意味があります。何故ダメなんですか？
