Which detail from “thomas edison: the master of improvement” develops the idea that edison was an improver, not just an inventor?

“thomas edison is well known as a great inventor. however, he was also a fantastic improver.”
“however, the first electric light was actually created by chemist humphry davy forty years before edison was born.”
“edison thought that the secret to a better bulb could be found in the filament. he simply needed to figure out what type of material worked best.”
“perhaps that is why he is believed to be the genius behind the lightbulb’s creation, while the names of the true inventors are unfamiliar today.”

"Thomas Edison" is well known as a "great inventor". However, he was also a "fantastic improver" is the correct answer.

Option (a);

EXPLANATION:

Thomas Edison is believed to be a landmark of inventions.  Light bulb was already invented by 'Humphry Davy' around forty years ago even when Edison was born. But those could not be used domestically at homes in a safer way. Edison invented a practical glowing light bulb for the first time.

Many people had worked and created some of the other forms of lighting. But nothing was such that could be used at homes practically. So, Edison developed 'incandescent light bulb' that was safe, practical and economical.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.

no the answer is c only objects touching the earth's surface can be acted upon by an outside force
