. Does Gladwell expect that readers will actually be able to use the information he provides? How can you tell?

Most of us were introduced to the concept of open-ended and closed questions when we were in teacher preparation programs. We were taught that an open-ended question was likely to draw out a longer response than a closed one. By turning a closed question that can be answered with a specific piece of information ("What answer did you get for number 5?") to an open-ended one that allows for more than one response ("How did you get the answer for number 5?"), we can provoke more insightful commentary from students. But open-ended and closed questions describe student response formats. Although these are important considerations for bolstering engagement, they don't fully address the teacher's purpose for asking either question in the first place.

answer: hmm i’ve done that before.. i’ll answer back when i move got it. i know i have the answer.. it’s on the tip of my tongue! don’t worry.. i’ll try to answer asap!

explanation:

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
