Answer 1

The Correct Option is D

The given passage is about Alexander Graham Bell and the invention of the telephone. The passage explains that Bell invented an instrument called the telephone. The passage also says that this invention was going to revolutionize life in the years to come. This means the telephone was not just a small invention for one person or one country. It changed the way people communicated with each other. Before the telephone, communication over long distances was slow and difficult. People mainly depended on letters, messengers, or telegraph systems. The telephone made it possible for people to speak directly to each other from distant places. This brought people, towns, and countries closer. Therefore, the main contribution of the telephone was that it changed human life in a very big way. Among all the options, option (D) expresses this broad impact correctly. Hence, the correct answer is: \[ \text{It revolutionized human life.} \]

Answer 2

The passage clearly tells us that Graham Bell was closely connected with the deaf and dumb. His father and his wife were also dedicated to the noble cause of teaching the deaf and dumb. Bell himself opened a school for deaf and dumb children. While working in this field, he became interested in sound, speech, hearing, and communication. The idea behind the telephone came from his work related to sound and speech. This means that his service to the deaf and dumb played an important role in leading him toward the invention of the telephone. Option (A), his activity of teaching, is related, but it is not as specific as option (B). Option (C), his keen interest in scientific inventions, is also connected, but the paragraph gives more importance to his service to the deaf and dumb. Option (D) is not the main reason according to the passage. Therefore, the correct answer is: \[ \text{His service to the deaf and dumb.} \]

Answer 3

The passage mentions that the Emperor of Brazil and the receiver of the telephone slipped from his hand. This event took place when the telephone was demonstrated. The passage states that Graham Bell was giving a demonstration of his invention at Philadelphia. It also refers to the Centennial Exhibition held in \(1876\). At this exhibition, Bell demonstrated the working of the telephone. The Emperor heard Bell's voice through the instrument and was surprised. So, the city connected with this important demonstration was Philadelphia. Edinburgh is connected with Bell's birth. Boston is connected with Bell's work in the United States. Brazil is connected with the Emperor, not the city of demonstration. Therefore, the correct answer is: \[ \text{Philadelphia.} \]

Answer 4

The paragraph says that Graham Bell was involved in teaching the deaf and dumb. Deaf and dumb children are physically underprivileged because they face difficulty in hearing and speaking. Teaching such children requires patience, kindness, skill, and dedication. That is why the passage calls Bell's work a noble cause. A noble cause means a work done for the welfare of others. Option (B) is not correct because the passage does not say that there was nobody else in education. Option (C) is not correct because the passage does not mention that Bell refused salary. Option (D) is also not the correct reason because being a famous scientist does not make teaching noble. The teaching work was noble because it helped children with physical difficulties. Therefore, the correct answer is: \[ \text{He was teaching the physically underprivileged persons.} \]

Answer 5

The passage tells us that Bell went to Canada in \(1870\). The reason mentioned in the passage is connected with his illness. Bell was suffering from illness, and therefore he was sent to Canada. This means the purpose of going to Canada was related to his own health. After going there, he continued his work and interest in teaching the deaf and dumb. But the immediate reason for going to Canada was not teaching. It was also not to treat another patient. It was not mainly to devote full time to the invention either. Therefore, the correct answer is: \[ \text{Undergoing medical treatment for himself.} \]
