A. How the deaf people communicate.
Step-by-step explanation:
46. In the 1700s, the deaf learned sign language. We can see this when the text says, "The language they used was a language without sound. It was a sign language."
47. A tap on the chin with three fingers means my uncle. It was after the explanation of how body language works. After that, there are two examples: the first one describes the sign that meant you are not telling the truth, and the second example describes the sign for my uncle. The text says, -They might tap their chins with three fingers. This meant “my uncle”-
48. Sign language helped the deaf to communicate with other people. As it says at the beginning of the text, before the 1700s, deaf people could not communicate because they could not use spoken language. Then, with sign language, they could express themselves and interact with others.
49. Sign language and fingerspelling are not used as much as they used to because there are other ways for deaf people to communicate. These ways are: understand others by watching their lips and teach deaf people how to speak. The text says, "Sign language and fingerspelling are not used as much as they once were. Today, the deaf are taught to understand others by watching their lips. They are also taught how to speak."
50. The main idea of the text is how deaf people communicate. The text describes: how deaf learned sign language to express themselves, the use of fingerspelling, and the most common ways that deaf people use today to understand and to interact with others, which are watching the speaker's lips and learning how to speak. In conclusion, they are all ways that deaf people use to communicate.
