Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Optical mice use an LED and a camera to rapidly
capture images of the surface beneath the mouse.
The infomation from the camera is analyzed by a
DSP (Digital Signal Processor) and used to detect
imperfections in the underlying surface and
determine motion. Some materials, such as glass,
mirrors or other very shiny, uniform surfaces
interfere with the ability of the DSP to
accurately analyze the surface beneath the mouse.

Since glass is transparent and very uniform, the
mouse is unable to pick up enough imperfections in
the underlying surface to determine motion.
Mirrored surfaces are also a problem, since they
constantly reflect back the same image, causing
the DSP not to recognize motion properly. When the
system is unable to see surface changes associated
with movement, the mouse will not work properly.
Solution: why doesn't an optical mouse work on a glass
table?
Reason: The passage talks about the glass and mirror surfaces beneath the optical mice and how the mouse is unable to pick up enough imperfections in the underlying surface to determine motion. The last line of the passage explains why the mouse will not work properly on these surfaces. Thus it is a positive example.

Now, solve this instance: From my personal experience, I've seen parental favoritism cause lifetime effects.
My mom's brother was the favorite- she was the least favored. 50 years later, she still struggles with feeling inadequate and has a hard time trusting people. Because of this, she has a hard time maintaining friendships and family relationships.
My grandmother and her sister were treated differently by my great-grandfather. My grandmother was treated as the most special. Her sister was expected to do chores, take care of the family etc. She ended up being the dependable, reliable one because she developed her independence. She also never forgave her father or her sister for their unfair treatment. My grandmother grew up needing others to take care of her.
This is a pattern I've seen. Those that are favored end up developing few of their skills and talents. Many times they grow up becoming more concerned about pleasing other people. And many times they don't know how to take care of themselves.
Those that are disfavored can become strongly independent, but they may also have weaknesses in their ability to trust others and form lasting relationships. What is true is that favoritism has an unhealthy emotional impact on all children, whether favored or not.
A good book that deals with this subject is The Emotional Incest Syndrome : What to do When a Parent's Love Rules Your Life, by Dr. Patricia Love.
