<em>For all intents and purposes </em>is an example of a cliche. A cliche is an overused expression to the point that it should be avoided in writing, if possible.
Answer:
Asking questions during reading.
Explanation:
While an engaging text would be better for increasing the number of students willing to read, it doesn't figure out their comprehension level. Establishing a purpose for reading gives kids the will to read, but doesn't identify their comprehension. Choosing a text with complex characters provides <em>more </em>for readers to suck in, and can get confusing. This <em>certainly</em> doesn't help read their comprehension. Therefore, the answer is "asking questions during reading."
It depends if you mean the proverbial parable from the Bible it would be know but if you mean like a story to teach a lesson then yes but most likely yes :) XD
