Question

some footraces are practically a walk in the park. sure, the 100 - meter sprint takes effort, but its run on an even track and finished in seconds. then theres the spartathlon. every september, hundreds of athletes from around the world gather in greece to run this nonstop 153 - mile (246.2 - kilometer) race in under 36 hours. and thats on rocky, muddy terrain that traverses vineyards, olive groves, hillsides, and most daunting of all, steep, craggy mt. parthenion...in the dark of night!
so, runners, on your mark, get set, and off we go to some of the worlds most extreme footraces.
the spartathlon follows the footsteps of an ancient greek long - distance messenger named pheidippides. about 2,500 years ago, greece was being invaded by persia and, according to a greek historian, it was pheidippidess duty to run from athens to sparta, two greek cities, to summon help. he made the 153 - mile journey in about two days, which the spartathlon now replicates. but the runners face an additional challenge - they must reach 75 individual checkpoints in a set amount of time, or theyre eliminated. unlike pheidippides, however, they can snatch food and water bottles at stations along the way.
question 1
this article is primarily about _______.
a. the regulations for the longest certified footrace in the world
b. historical facts about long - distance running in greece
c. footraces that provide athletes with unique challenges
d. the winter weather conditions that occur in the arctic circle

Explanation:

The article begins by contrasting the 100 - meter sprint (a relatively simple footrace) with the Spartathlon (a non - stop 153 - mile race on rough terrain). It then goes on to describe the Spartathlon in more detail, including its historical origin (following the footsteps of Pheidippides) and the unique challenges it presents (such as reaching checkpoints on time). Option A is incorrect because the article is not mainly about regulations. Option B is too narrow as it's not just about historical facts in Greece but also the modern - day race and its challenges. Option D is completely off - topic as the Arctic Circle is not mentioned. Option C is correct as the article focuses on footraces (specifically the Spartathlon) that offer unique challenges.

Answer:

C. footraces that provide athletes with unique challenges
