GED Reading: The Book of Evolution

Hola! I’m not so good at science in the first place, but sometimes science can be interesting. Like the theory of evolution. It says that we all evolved from the fish or something like that. I don’t know a lot about it, but I can’t imagine my great great great bisabuela having fins or gills. Or being some sort of bacteria. A lot of people have debates about whether or not we evolved from something else, or if certain theories about the beginning of the world, like in the bible, are correct.

It’s all interesting stuff, but sometimes if we want to know more about it, we gotta read science books, like On the Origin of Species by Charles Darwin. He’s the guy who came up with this idea of evolution. I don’t know if he thought we all came from some sorta primordial soup though. I think he just mostly noticed that animals can change to fit their environment, and that eventually all of that species changes too. Here’s a paragraph from his book:

If we suppose any habitual action to become inherited—and I think it can be shown that this does sometimes happen—then the resemblance between what originally was a habit and an instinct becomes so close as not to be distinguished. If Mozart, instead of playing the pianoforte at three years old with wonderfully little practice, had played a tune with no practice at all, he might truly be said to have done so instinctively. But it would be the most serious error to suppose that the greater number of instincts have been acquired by habit in one generation, and then transmitted by inheritance to succeeding generations. It can be clearly shown that the most wonderful instincts with which we are acquainted, namely, those of the hive-bee and of many ants, could not possibly have been thus acquired.

What point is the author trying to make in this passage?

1. Talented people inherit their abilities.

2. It is difficult to know the difference between a learned habit and an inherited one.

3. Learned habits and inherited habits are the same thing.

4. Animals can not learn.

5. People do not have instincts. Continue reading

GED Reading Practice Question 10: Main Idea

One of the things the GED test asks you to do is find the main idea of something you’re reading. But here’s a hint… it doesn’t necessarily say, “What’s the main idea?” You have to look at the question and realize that they want you to figure out what’s the main idea of what you read. To understand the main idea of a GED reading, you need to read the entry and then think about what it’s trying to say overall. What’s the most important thing? What’s the big picture? Continue reading
