closer to reality. Researchers have investigated the use of electricity to stimulate vision for nearly half a century. In the 1960's, a *physiologist implanted 80 electrodes on the surface of a blind person's *visual cortex, a region at the back of the brain. Wireless stimulation of the electrodes made the patient see spots of light known as *phosphenes. This is the first stop for visual signals coming from the eye. (D) By the 1980's, a crop of *ophthalmologists began considering a narrower and seemingly easier-to-solve problem: making *prostheses for the eye. They suggested that degrade *photoreceptor cells called *rods and cones, still leave large portions of the retina intact even after a patient has become totally blind. The way to stimulate the remaining functional cells was proved *feasible in the mid-1990's. A device consisting of a tiny video camera perched on the bridge of a pair of glasses, a belt-worn video processing unit, and an electronic box, was developed recently. The electronic box issues signals to an implant behind the patient's ear that has wires running to a grid of 16 electrodes affixed to the output layer of the retina. The video processor wirelessly transmits a simplified picture of what the camera images to the box, and then the retinal implant stimulates cells in a pattern roughly reflecting that information.

(6)の模範解答が⭕️なのですが、問題文にはwhen Nightingale was young とあり、文中の黄色マーク🟡で引いた該当する文は、彼女が30歳になった時のことを言っているのから❌ではないのですか?教えてください🙏😭

次の英文を読んで、(1)~00までの文がその内容とあっていれば〇をそうでなければ×を解答 用紙に記入しなさい。 Florence Nightingale Florence Nightingale was born on May 12, 1920, into a wealthy family in England, and received the most luxurious education from an early age, learning not only foreign languages like French, Greek, and Italian, farmers she visited for charity work, she gradually began to think that she wanted to work in a job that but also mathematics, astronomy, psychology, and literature. However, after seeing the lives of poor served people. When she turned 30, she decided to become a nurse and started working at a hospital in London. Nightingale, who eventually became a director of a women's hospital, began to advocate the need for nurses with specialized training. At that time, nurses had a low status and were considered nothing more than servants who cared for the sick. A major turning point occurred in 1854. War began in Crimea*, present-day Ukraine, and Nightingale was sent there with 24 Catholic sisters and 14 nurses. Nightingale's efforts improved the hospital environment during the war. The Nightingale School of Nursing was established with the Nightingale Fund created during the war. Although Henri Dunant, a founding member of the International Committee of the Red Cross, highly praised her work, Nightingale was not involved in the International Committee of the Red Cross. This was because she believed that aid activities based on self-sacrifice by participants would not last long. Her famous quote, "Devotion without sacrifice is true service," expresses this well. It is said that this was due to the idea that "we rely on the spirit of service of our members, but without financial support, we are powerless." Nightingale only served wounded soldiers as a nurse for only two years during the Crimean War*, and became famous for her symbolic image of dedication and for her use of statistics to reform health care. The statistical methods she used at this time were highly praised, and she was considered a pioneer of statistics in England. Nightingale suffered from poor health from a young age, and is said to have spent most of her time in bed after returning from Crimea. Nightingale passed away peacefully at the age of 90 at her home in London on August 13, 1910. advocate* 主張する Crimea* クリミア半島 Crimean War* クリミア戦争 (1) Florence Nightingale was born in a wealthy family and she learned many foreign languages.
