⑷の棒線部の訳がわかりません。問4が答えです。主語はないのですか?

23 15m 20 min. 362 words 次の英文を読んで、設問に答えなさい。 (1) A lot of people think cancer is the number one killer in the United States, but it's not. The leading killer is heart disease. Cancer is number two. Heart disease is responsible for about one-quarter of the deaths in the U.S. each year. Heart attacks (2a) account for over 500,000 deaths a year. One 5 reason the number of deaths from heart attacks is so high is that when people experience chest pain, they don't realize they may be having a heart attack and wait too long before going to the hospital. Such a delay can be fatal. (3a)- In fact, more than half of all heart attack victims die before they reach the hospital. 10 What are the warning signs of a heart attack? According to the American Heart Association, the signs include uncomfortable pressure or pain in the middle of the chest for two minutes or longer; movement of pain to the shoulder, arm, neck, or jaw; sweating may accompany the pain; *nausea and vomiting may 15 also occur; and shortness of breath, dizziness, or fainting may be experienced with the other signs. (3b) One of the factors that increase the risk of heart attack is high blood pressure. Today, with the stresses of everyday life, nearly one out of every three adults suffers from high blood 20 pressure. High blood pressure can be brought on by a fight with one's *spouse, problems at work, (2b) speaking in public, or even telling a lie. But it can also be brought on by something you enjoy, like the caffeine in a cup of coffee, cigarettes, or alcohol. There are, fortunately, ways to lower blood pressure - ways 25 Introduce
