Definition: You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Input: The answer, of course, varies for each individual depending on how fit you are, how often do you train and what your goals are.

If you are very aggressive, you can do it in 28 weeks. Start by walking, slowly, for a
mile. Two days later, walk 1.5 miles. Every other day, increase the distance by half a mile until you get to 3 miles. Rest your muscles on the "off" day. Hold that distance on Tuesday and Thursday, while increasing by one additional mile on your weekend session (either Sat or Sun).

Once the long walk reaches 10 miles you can cut the distance in half every other weekend, increasing the long one by 2 miles each time. When the long one
gets to 18 miles, you can do it every third weekend, covering 8-9 miles on the "short" weekends.

After about the third week of training, insert a one min jog into your runs, after 4 min of walking. If this feels fine after 2 weeks, drop to 3walk/1jog. After 3 more weeks, drop to 2-1. If all goes well after another 3 weeks or so you could go to 1-1 during the week, and 2walk/1jog on the long run.

Find the ratio that works best for you, that will leave you feeling strong at the end, and recovering fast from these long ones. The pace for all of
these should be very, very slow.
Output:
As a novice runner, how many weeks/months do I need to properly train for a marathon?
