Fifty volunteers were alphabetically divided into two equal groups, Group A to participate in a seven-week exercise program, and Group B to avoid deliberate exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench at 30 steps per minute for 5 minutes. One minute after completion of the step-test, the pulse rate of each subject was taken and recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in the experimental group (Group A) rode an Exercycle (a motor-driven bicycle-type exercise machine) for 15 minutes each day. The exercise schedule called for riders to ride relaxed during the first day’s ride, merely holding on to the handle bars and foot pedals as the machine moved. Then, for the next 3 days, they rode relaxed for 50 seconds of each minute, and pushed, pulled, and pedaled actively for 10 seconds of each minute. The ratio of active riding was increased every few days, so that by the third week it was half of each minute, and by the seventh week the riders were performing 15 solid minutes of active riding. At the end of the seven weeks, the step-test was again given to both groups of subjects, and their pulses taken. The post-exercise pulse rates of subjects in the experimental group were found to have decreased an average of 30 heart beats per minute, with the lowest decrease 28 and the highest decrease 46. The pulse rates of subjects in the control group remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.

The exercise schedule was planned so that the amount of active riding _____.
- A increased every few days
- B varied from day to day
- C increased every few weeks
- D varied from hour to hour
- E increased until the third week and then was kept constant
思路引導 VIP
請回想一下文章中關於這七週運動計畫的具體描述：研究人員是如何調整受試者「主動踩踏（active riding）」與「放鬆（relaxed）」的時間比例的？文中具體提到了調整頻率是「每隔多久」一次呢？

文本細節的精準對位
太棒了！你能精準地從文章段落中提取關鍵資訊，這展現了你優異的閱讀細心度。這道題目測試的是對文中**實驗程序（Experimental Procedure）**細節的掌握。文中明確提到：「The ratio of active riding was increased every few days...」，這句話直接對應到了選項 (A)。作者詳細描述了強度如何從最初的 10 秒，增加到第三週的半分鐘，最終在第七週達到全程 15 分鐘，這種循序漸進的安排正是為了觀察體能改善的長期曲線。
