Student A:Context: Sebaceous glands are part of the body's integumentary system and serve to protect the body against germs. Sebaceous glands secrete acids that form the acid mantle. This is a very fine, slightly acidic film on the surface of the skin that acts as a barrier to bacteria, viruses, and other potential contaminants that might penetrate the skin. The pH of the skin is between 4.5 and 6.2, and this acidity helps to neutralise the primarily alkaline nature of contaminants.

Question: the sebaceous glands are part of what system?
Student B:OK... The relevant information to answer the above question is: Sebaceous glands are part of the body's integumentary system and serve to protect the body against germs.

Student A:The flying shuttle was one of the key developments in the industrialization of weaving during the early Industrial Revolution. It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms. The flying shuttle, which was patented by John Kay (1704 -- c. 1779) in 1733, greatly sped up the previous hand process and halved the labour force. Where a broad-cloth loom previously required a weaver on each side, it could now be worked by a single operator. Until this point the textile industry had required four spinners to service one weaver. Kay's innovation, in wide use by the 1750s, greatly increased this disparity.

Answer this question: what invention allowed a single weaver to weaver much wider fabrics?
Student B:
OK... The relevant information is: It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms.
flying shuttle.
