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.
Part 2. 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.
\nSince 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.
Answer: why doesn't an optical mouse work on a glass
table?
Explanation: 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.
Part 3. Exercise
Easter celebrates the raising of Jesus from the dead, this is the actual point at which the Christian Church began as Jesus appeared to his disciples:\n\nMatthew chapter 28 (TEV)\n\n16 The eleven disciples went to the hill in Galilee where Jesus had told them to go. 17 When they saw him, they worshiped him, even though some of them doubted. 18 Jesus drew near and said to them, "I have been given all authority in heaven and on earth. 19 Go, then, to all peoples everywhere and make them my disciples: baptize them in the name of the Father, the Son, and the Holy Spirit, 20 and teach them to obey everything I have commanded you. And I will be with you always, to the end of the age."\n\nSo as undoubtedly important as Christmas is marking the birth of our Lord, Easter is thefoundation of the Church, and our promise of everlasting life in Heaven.
