Question

As heart disease continues to be the number one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and ''life in the fast lane'' have long been known to contribute to the high incidence of heart failure. But according to the new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980 and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between hours of 8 A.M and 10 A.M,

In other studies, both birthday and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all the aforementioned risk factors, intense research continues in the hope of future comprehending why and how heart failure is triggered.

According to the passage, which of the following is NOT a possible cause of many heart attacks? 
A. Decreased blood flow to the heart 
B. Increased blood pressure 
C. Lower heart rate 
D. Increase in hormones 
E. Rise concentration of heart stimulating hormones

Halo Siti A, kakak bantu jawab ya.

Jawaban untuk soal di atas adalah C. Lower heart rate.

Soal ini menanyakan yang bukan merupakan kemungkinan penyebab banyak serangan jantung.

Pada akhir paragraf kedua disebutkan "An early-morning rise in blood pressure, heart rate and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks...." yang artinya "Peningkatan tekanan darah, detak jantung dan konsentrasi hormon perangsang jantung di pagi hari, ditambah pengurangan aliran darah ke jantung, semuanya dapat berkontribusi pada insiden serangan jantung...."

Dengan demikian, dapat disimpulkan bahwa yang bukan merupakan kemungkinan penyebab banyak serangan jantung adalah penurunan detak jantung.

Jadi, jawaban yang benar adalah C. Lower heart rate.

Semoga membantu ya.
