Article: Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too. There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.
Question: The early language had _ .
Options: (A) a lot of problems (B) words and easy grammar (C) words but no grammar (D) grammar but not many words
D

Article: The latest fashion in kitchen is the food steamer. All the stores are selling them; everyone wants one. Steaming is one of the simplest and healthiest ways of cooking food.However, that cooking time is usually longer than with other methods. In case you're thinking of buying a steamer, I've done a survey about the steamers available on the market to help you decide which will suit you best. *Folding Steamer The simplest and least expensive is the folding stainless-steel version. Advantages: This is a good, basic design which sits inside a variety of different shapes of pans with the water under it; a ring in the center allows for easy lifting and it's easy to clean. Disadvantages: It only holds small dishes. Also, if you put too much water in the pan, it will boil up through the vegetables and they will be watery. If you put too little water in and let it get dry, you will burn the pan and get strange-smelling vegetables. *Steaming Pan This is a three-layered black Teflon-coated version with a lid and two double-handled steamers, which sits on the oven ring. The brand I bought is called Nutritious Living. Advantages: This is an excellent steamer, lightweight, easy to clean, and of all the steamers I've tried, this cooks the fastest. Fish and chicken can be cooked on the bottom with rice or vegetables on the top. It's easier to store. Disadvantages: Water can boil away until the pan is dry, but if you make sure you fill the pan up to the suggested level and do not overcook the food, this should not happen.You cannot see the food cooking from the top. It doesn't supply a dish for cooking rice. For serious users of steamers, I recommend having one of each version. If you just want to try it, get the folding stainless-steel type.
Question: Why did the author carry out the survey?
Options: (A) To inform people of different steamers (B) To run an advertisement for steamers (C) To find out a suitable steamer to buy (D) To learn how to cook with steamers
