  1. For- For means because. One does not understand importance because of physical exercise but understands the importance of physical exercise. So, the correct word is “of”.
  2. Spend- With pronouns (he/she/it) describing an individual, ‘s’ is added at the end of the words. So, the correct word is “spends”.
  3. On- ”On” is a preposition which usually tells about the position of an object/human which is situated or kept above a certain object and one is not situated above air. So, the correct word is “in”.
  4. When- “When” is used to describe a time or date of the event and is not used to point at a specific event. So, the correct word is “which”.

Thus, the correct paragraph is

The Modern Student understands

importance of Physical exercise.

He spends one or two hours daily

in the open air where he takes   

part on Exercises which work

wonders for His Health.
