In this task, you're given a context passage, followed by a question that needs to be answered. Based on the paragraph, you must write unambiguous answers to the questions and your answer must refer to a specific phrase from the paragraph. If multiple answers seem to exist, write the answer that is the most plausible.

My hair is dirty and feels oily when I touch it today, so it is time to wash it. I like washing my hair in the shower because it is much easier than in a bath tub. I turn the shower on and make sure the water is nice and warm, but not too hot. I step in the shower and get my hair nice and wet. It is good to use shampoo and conditioner. First, I take some shampoo that I like and rub it onto my head. This cleans the part of the hair that is close to your head and also cleans the skin there that gets oily. After the shampoo is rubbed into my head, I let the water from the shower rinse out all the soap. Once the soap is out, I take some conditioner and rub it into the longer parts of my hair and the ends. This keeps it nice and soft and healthy. I let the conditioner sit in my hair for a while, and then rinse it all out in the warm water. I dry off, and feel better knowing that my hair is nice and clean again. 
Question: Were they talking to someone while they washed their hair?
Probably not.

Halsey's Planet is in decline, and when a generation ship arrives, having failed to contact six other planets, Ross is sent to discover the state of the interstellar colonies. He is given a ship which can make the trip from colony to colony almost instantaneously. The technology used in the ship has been kept secret because it could give rise to interstellar war if one colony decided to conquer others. However, the isolated populations are also affected by genetic drift resulting in a decline in their societies. The first planet he visits has been completely destroyed, the second is a gerontocratic travesty of a democracy, and the third is a repressive matriarchy. On the way he picks up companions Helena and Bernie. The next planet they visit is supposed to be Earth, but it turns out not to be; not only are its planetary statistics different from Earth's, but it is populated by a race of almost-identical people called Joneses. This planet, also called Jones, is ruled by a cult of total conformity in all areas of life, including genetic phenotype. Ross discovers that the equation whose meaning he has been seeking refers to the loss of unfixed genes in a small population, which explains the degeneracy of the planets he has visited. Dr. Sam Jones learns that he has been worshiping an equation on genetic drift, and joins the little band. They sort out their navigational problem and finally make it to Earth, which is a civilisation of morons protected by a small minority of hidden geniuses, like the situation in "The Marching Morons". Ross realises that the problem with all the degenerate worlds is their isolation; luckily he has the FTL drive and so sets about rectifying the problem by bringing them together. 
Question: Who protects the morons on earth?

A small minority of geniuses.
