Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 39 to 43.

When I surveyed over 5,000 middle grade students for my book, kids were already reminding me of the technology gap between them and their parents. They claimed that parents “didn’t have a clue” as to what they were experiencing on screens. While generation gap is often characteristic of adolescence in any generation, it is even wider because of rapidly changing technology.

Even the guidelines I prescribed six years ago would be impossible to implement for this generation of tablets, cellphones and notebooks that travel in children’s backpacks. Setting and enforcing guidelines early for children is helpful. Taking technology away at bedtime is still possible and at least allows them a good night’s rest. Cautioning your children about not sharing real names, addresses or phone numbers in chatrooms or for any emails protects them somewhat. Making sure your hardworking home is balanced by non-screen family fun can be enormous protection. Beware of over-consequencing and over-punishing for small problems. We don’t want your children to think of their parents as enemies in a battle of wills.

Tell your children how wise and experienced you are and how much you love them at least five times a week. They need to know they can count on you in this complex, fast-moving world even if they know more about technology than you do. Like every generation, your children will grow up and hopefully find responsible directions for their own lives. Technology skills are valued in the work force and technology is here to stay. Learning as much about it as possible will help you stay tuned-in to what your children aren’t saying.
