If you've ever shopped for produce in a U. S. grocery store, you've probably seen yams and sweet potatoes on display. Generally, the ones labeled "yams" have reddish skin and orange flesh, while the sweet potatoes have gold-colored skin and white flesh. Yet scientifically speaking, those yams aren't yams at all; they're really a variety of sweet potato. True yams are native to Asia and Africa and belong to their own family of plants. They have rough, bark-like brown skin and dry, starchy flesh. True yams are not often stocked in U. S. grocery stores. Sweet potatoes, on the other hand, belong to the morning glory family of plants and are widely grown in the United States. Unlike true yams, which are tubers, or
underground stems, sweet potatoes are roots, like carrots.

What is the main idea of the passage?
A:True yams are grown in Asia and Africa and are not often sold in the United States.
B:True yams are tubers, or stems, while yams sold in U. S. grocery stores are roots.
C:True yams are starchy tubers from Asia and Africa, while U. S. yams are a type of sweet potato.

A:True yams are grown in Asia and Africa and are not often sold in the United States.

This is correct because the author starts comparing the two yams at the end and we realize the U.S doesn't even have yams and they are mistaken. They really grow in Asia and Africa is what the main idea is.

B is not correct because it is just the description of the yam, but it wasn't the point of the passage. The author used this detail to get to the main idea.

C is not correct because of the misinformation. While the first half of the answer is true about Asia and Africa grown yams, it says then they are a sweet potato in the U.S. That's what they are said as in the U.S, but the point of the passage was to clear up what yams really are and where they originate.

A:True yams are grown in Asia and Africa and are not often sold in the United States.

Explanation:

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).
