Final answer:
The statement about the stringer bead is false as it is not used for wider weld pools. The high-voltage wire being wrapped in insulating material is false, they are bare and held by insulators. Both statements about the preference for short staple cotton before the cotton gin and Francis Cabot Lowell building the first integrated textile mill in New England are true.
Step-by-step explanation:
The statement that a stringer bead is used to create a wider weld pool is false. A stringer bead is actually a type of weld bead that is run straight and used primarily for narrow welds, not for creating a wider weld pool. If the goal is to create a wider weld, a weave bead technique would typically be used instead.
The high-voltage wires that are connected to tall metal-frame towers are indeed held aloft by insulating connectors to prevent electricity from grounding, but these wires are actually not wrapped in an insulating material. The statement is therefore false. High-voltage transmission lines are typically bare wires because the surrounding air provides enough insulation, and covering them would add unnecessary weight and reduce efficiency.
Regarding the preference for cotton types prior to the invention of the cotton gin, it is true that short staple cotton was preferred over long staple cotton. This is because the long fibers of the long staple cotton were difficult to clean and separate from the seeds by hand. The cotton gin, invented by Eli Whitney in 1793, made it much easier to process short staple cotton, which prior to that had been a labor-intensive and thus less desirable crop.
Finally, the statement about Francis Cabot Lowell is true. Lowell indeed built the first integrated textile mill in New England, which combined all phases of production from spinning to weaving in one facility, marking the beginning of the factory system in America.
