Power on 2のLesson 6です!写真が本文なのですが、Part 3にはいくつの長所が書かれてますか?

Tas Lesson6 Vegetable Factories 予習プリント PAF Task-1: Translate underlined parts into Japanese C C PART 1 Takumi: Angelina, have you ever heard of vegetable factories? I learned about them for the first time on TV last night. Such factories were first built in Denmark in 1957, and similar factories were PAI also introduced in the US in the 1970s. Angelina: Vegetable factories-yes, 1 know about them, too. In Japan, they were first built in the early 1980s to produce kaiware sprouts. These factories are now attracting much attention as a new type of agriculture I hear new vegetables like frilice lettuce and ice plant are being produced there. Takumi: Wow! You really knowa lot about vegetable factories. Angelina: Would you like to know more? Takumi: Definitely! もちろみ に C フリルレタズ C PA C C C PART 2 C You may be surprised to hear that we can grow vegetables without the sun and soil. But that is what people do in vegetable factories. In these factories, electric light and fertilized water are used instead of the sun and soil. Temperature and humidity are also controlled. It seems that limited space in vegetable factories is not a big problem. Workers fully use the space by stacking shelves of vegetables. Actually, you can find small vegetable factories in the previolisly wasted space of office buildings or restaurants. At present, the main crops from vegetable factories are leaf vegetables. But in the near future, PA C C Ta more varieties of vegetables are sure to come. し]必ず…する PART 3 What are the good points of vegetable factories compared to traditional agriculture? For one thing, they can provide a stable supply of vegetables, even in bad weather conditions. For another thing, vegetables grow much faster in a controlled environment. Other good points include no use of chemicals and good taste with more vitamins. Unfortunately, vegetable factories still face one challenge. Running them requires a lot of money. Because of this cost, these vegetables are expensive to buy. Hopefully, in the near future, we will have solved this problem. うまくいけば PART 4 文に、科に Talkumi: Agriculture without the sun and soil. Hmm. That's a great idea indeed. Honestly, Ive got a bit of, ahem, “agriculture shock" from what you've just told me in a good way though. Angelina: Ha-hal Have you? Good. If we can develop vegetable factories on a large scale, we may be able to solve the problem of food shortages. Takumi: Yeah, I agree. And the way we view vegetables may change whether we like it or not. Oh, by the way, Angelina, culture and agriculture are closely related, as you can see from the words. Agri-means “farming," and culture means “to grow something." Angelina: Oh, so you're giving alecture now! 422words

ものすごく至急です💦今日授業で当てられそうなのですか答えが確実じゃなくて焦っています 答えだけでいいのでほんとうによろしくお願いします 根拠の場所あれば教えて欲しいです

次の英文を読み,下の問いに答えなさい。 We all know the saying “To err is human." And this is true enough. When somethine 80es wrong, the cause is overwhelmingly attributed to human error: airplane crashes (70 percent), car wrecks (90 percent), workplace accidents (also 90 percent), You name it, and humans are usually to blame, And once a human is blamed, the inquiry usually stops ans ISL stu an 止 there. But it shouldn'tー atleast not if we want to eliminate the error. S In many cases, our mistakes are not our fault, at least not entirely. For we all have certain biases" in the way we see, remember, and perceive the world around us, and these biases make us commit certain kinds of errors, Right-handed people, for instance, tend to turn right when entering a building, even though that may not afford the best route to take. And most of us, whether left- or right-handed, show a preference for the number 7 and the color blue. We are also so persuaded by our first impressions of things that we are reluctant to change our first answer on a test; yet many studies have shown we would be better off if we did exactly this. Qur expectations can shape the way we see the world and often the way we act in itas well, In one case, people encountered an unknown man and were later told his occupation. When they were told that the man was a truck driver, they said he weighed more%; when they were told he was a dancer, they said he weighed less. In another case, half the people in a restaurant were told their free glass of wine that night came from France; the other half were told their wine came from somewhere else. Not only did the second group eat less of their meals, but they headed for the doors more quickly. Farmers too show the same tendency. Farmers who believe in global warming, for instance, have been shown to remember temperatures as being warmer than those recorded in statistical tables, And what about farmers who do not believe in global warming? They remembered temperatures that were colder than those in the record books. What's important about these examples is not that we think a truck driver is fatter than a dancer or that temperatures are warmer than they used to be. What'simportant is that these effects occur largely outside of our consciousness; we're biased ー we just don't know we' re biased. Some of these tendencies are so strone that eyen_when_we do know
