Answer:
British mathematician William Bourne made some of the earliest known plans for a submarine around 1578, but the world’s first working prototype was built in the 17th century by Cornelius Drebbel, a Dutch polymath and inventor in the employ of the British King James I. Drebbel’s sub was probably a modified rowboat coated in greased leather and manned by a team of oarsmen. Sometime around 1620, he used it to dive 15 feet beneath the River Thames during a demonstration witnessed by King James and thousands of astonished Londoners. Unfortunately, none of Drebbel’s plans or engineering drawings has survived to today, so historians can only guess about how his “diving boat” actually operated. Some accounts say it submerged via a collection of bladders or wooden ballast tanks, while others suggest that a sloping bow and a system of weights were used to propel the boat underwater when it was rowed at full speed.

Explanation:
The 1800s was a year that saw the First Industrial Revolution. This revolution brought about new processes and methods of producing and manufacturing.
An with that, the working conditions were as terrible and brutal as they can be. While adults were made to work in big factories with machines in a crowded space, with hardly enough pay and unhealthy atmospheres, children were also hired for their cheap labor.
So, the statement that best describes the working conditions in the mills in the 1800s was that <u>some workers suffered from health problems like cough due to the unsafe working conditions.</u>
