Đáp án D
Theo đoạn 2, thông tin nào về công việc tình nguyện KHÔNG được được ủng hộ bởi các nghiên cứu?
A. 100 giờ hoạt động tự nguyện là đủ cho một lợi ích sức khỏe nhất định, nhưng bệnh huyết áp thấp đòi hỏi gấp đôi số giờ đó
B. Chỉ cần 100 giờ tình nguyện mỗi năm để gặt hái được một lợi ích sức khỏe
C. 200 giờ hoạt động tự nguyện nên được dành ra hàng năm để ảnh hưởng đến mức độ huyết áp
D. Những công việc đòi hỏi trí tuệ giúp nâng cao năng lực trí tuệ trong khi những công việc thể chất có lợi cho tim và lưu lượng máu
Căn cứ vào thông tin đoạn hai:
"In the Carnegie Mellon study, 200 hours of volunteering per year correlated to lower blood pressure. Other studies have found a health benefit from as little as 100 hours of volunteering a year."
(Trong nghiên cứu của Carnegie Mellon, 200 giờ tình nguyện mỗi năm có liên quan đến bệnh huyết áp thấp. Các nghiên cứu khác đã nhận thấy một lợi ích sức khỏe sẽ đạt được từ ít nhất 100 giờ tình nguyện một năm.)
=> Thông tin trên cho thấy các đáp án A, B, C đều không sai. Do đó, đáp án D sai.
