Both the passage and the lecture discuss living on asteroids. The reading proposes three reasons that living on them will be a good idea. On the other hand, the professor states that those reasons are impractical and opposes each one.
First, the passage indicates that because those asteroids are smaller than Moon or Mars, they have lower gravity. As a result, it is safer to land on them. Also, spaceships can carry more equipment there and need less fuel. Nevertheless, the professor denies this view and illustrates that low gravity will have certain risks. He explains that people lose muscle structure, and their bone density gets damaged. Astronauts who live in low-gravity places for a few months suffer those problems, so colonists who will live for many years will be severely damaged.
Second, the reading claims that asteroids contain a significant amount of rare and expensive materials, such as gold and platinum. Colonists and businesses can use those materials to pay and support such a trip. Nonetheless, the lecturer rejects this idea and states that the cost of mining and transporting those materials to earth will decrease the profit. Also, if they have quite a lot of those rare materials, the market price will decrease. Therefore, they cannot make too much money out of them.
Finally, the author states that some of those asteroids come close to the earth, much closer than Moon or Mars, which will make it easier to get there and come back. However, the speaker refutes it, saying that getting there may be easy, but the return will be difficult. He says that some of those asteroids orbit unusually. They may get close to the earth, but they do not stay and move far away from our planet. As a result, getting back from there will be much challenging.
