Which sentence serves as the best introductory sentence to the above paragraph?
a) i am not too ashamed to admit my extreme addiction to technology.
b) technology is a double-sided sword with both good and bad qualities.
c) the so-called addiction teenagers have to technology has been vastly overstated.
d) families today are coming up with creative ways to break teenager's addiction to technology.

Families today are coming up with creative ways to break teenager's addiction to technology.

Explanation:

Four sentences out of six in the paragraph refer to the struggle 'to break teenager's technology dependency' and how different families try to solve this problem.

"In an effort to remind teenagers that technology is not essential to life, some parents are rationing out screen time for the week. Other parents don't allow their children to watch any television during the school week. Some families are even taking week-long camping trips in which no technology is allowed at all--even a cell phone. The struggle to break technology dependency is constant."

It is only logical that the introductory sentence should be

"Families today are coming up with creative ways to break teenager's addiction to technology."

11-32. the main character in the parable, the forgiving father, whose character remains constant throughout the story, is a picture of god. in telling the story, jesus identifies himself with god in his loving attitude to the lost. the younger son symbolizes the lost (the tax collectors and sinners of that day, luke 15: 1), and the elder brother represents the self-righteous (the pharisees and teachers of the law of that day, luke 15: 2). the major theme of this parable seems not to be so much the conversion of the sinner, as in the previous two parables of luke 15, but rather the restoration of a believer into fellowship with the father. in the first two parables, the owner went out to look for what was lost (luke 15: 1-10), whereas in this story the father waits and watches eagerly for his son's return. we see a progression through the three parables from the relationship of one in a hundred (luke 15: 1-7), to one in ten (luke 15: 8-10), to one in one (luke 15: 11-32), demonstrating god’s love for each individual and his personal attentiveness towards all humanity. we see in this story the graciousness of the father overshadowing the sinfulness of the son, as it is the memory of the father’s goodness that brings the prodigal son to repentance (romans 2: 4).
