I believe the correct answer is artificial.
Mary Wollstonecraft’s “The Vindication of the
Rights of Woman” had for the main purpose to convince the readers to accept her
point of view – that women’s weakness was artificial. She believed that women’s
minds were “flowers planted in soil that is too rich”, so they had no
weaknesses compared to men.

Answer:
Joseph Swan began working on a lamp using carbonized paper filaments, while Thomas Edison initially attempted to use metallic filaments.
Explanation:
Several names are mentioned when it comes to the research that involves the development of the lamp, but the most outstanding ones, because they made commercialization possible, were the British physicist and chemist Joseph Swan and Thomas Alva Edison.
In 1850 Swan began working on a lamp using carbonized paper filaments in an evacuated glass bulb. In 1860 he was able to demonstrate a working device, and obtained a British patent partial vacuum coating, carbon filament incandescent lamp. However, lack of a good vacuum and an adequate electric source resulted in an efficient light bulb with a short shelf life.
On the other hand, Edison initially tried to use metallic filaments. It took enormous investment and thousands of attempts to discover the ideal filament: a partially charred cotton thread. Installed in a vacuum glass bulb, it was heated with the passage of the electric current until it became incandescent, without melting, sublimating or burning. In 1879, a lamp so constructed shone for 48 continuous hours, and at the end of the year celebrations, a whole street, next to the laboratory, was lit for public demonstration. A few years have passed and Thomas Edison, before being able to make the idea of the lamp work, admitted that he had created 100 wrong ways to build a light bulb.
