Read the excerpt from The Story of My Life by Helen Keller.

Dr. Bell advised my father to write to Mr. Anagnos, director of the Perkins Institution in Boston, the scene of Dr. Howe's great labours for the blind, and ask him if he had a teacher competent to begin my education. This my father did at once, and in a few weeks there came a kind letter from Mr. Anagnos with the comforting assurance that a teacher had been found. This was in the summer of 1886. But Miss Sullivan did not arrive until the following March. P

Which excerpt from tinker v. des moines shows how precedent support an argument? a. "as we shall discuss, the wearing of armbands in the circumstances of this case was entirely divorced from actually or potentially disruptive conduct by those participating in it. it was closely akin to 'pure speech' which, we have repeatedly held, is entitled to comprehensive protection under the first amendment. cf. cox v. louisiana, 379 u. s. 536, 555 (1965); adderley v. florida, 385 u. s. 39 (1966)." b.

(1) fire extended humans’ geographical boundaries by allowing them to travel into regions that were previously too cold to explore. (2) it also kept predators away, allowing early humans to sleep securely. (3) fire, in fact, has been a significant factor in human development and progress in many ways. (4) other obvious benefits of fire are its uses in cooking and in hunting. (5) probably even more important, however, is that learning to control fire allowed people to change the very rhythm of their lives. (6) before fire, the human daily cycle coincided with the rising and setting of the sun. (7) with fire, though, humans gained time to think and talk about the day’s events and to prepare strategies for coping with tomorrow. the sentence that expresses the main idea is: (type the number of the sentence. then click “go.”)

Read this excerpt from wheels of change by sue macy. that said, it's hard to grasp the full extent of the bicycle's impact on americans in the late 19th century—particularly female americans. imagine a population imprisoned by their very clothing; the stiff corsets, heavy skirts, and voluminous petticoats that made it difficult to take a deep breath, let alone exercise. add to that the laws and social conventions that cemented a man's place as head of the household and holder of the purse strings. how suffocated women must have felt. and how liberated they must have been as they pedaled their wheels toward new horizons. what is the central idea of the excerpt
