While surfing in hawaii marcus was thrown by a huge wave that caused his surfboard to hit his head which caused him to temporarily lose consciousness and almost drown. after being revived by a fellow surfer, marcus reported seeing a light in a tunnel which he felt compelled to enter. this experience can be explained as being caused by: ?

This experience could be caused by a few different things. One of which could be losing consciousness and then coming to. Another explanation could be that Marcus got a concussion when he hit his head. A concussion can cause headache, blurred vision and seeing spots. So, it's possible his vision was very blurred and he was seeing the sun or some other light that made it look like he was looking down a tunnel. It seems more than likely that the light at the end of the tunnel was probably caused by him losing consciousness, though.

Early 18th century british industries were generally small scale and relatively unsophisticated. most textile production, for example, was centred on small workshops or in the homes of spinners, weavers and dyers: a literal ‘cottage industry’ that involved thousands of individual manufacturers. such small-scale production was also a feature of most other industries, with different regions specialising in different products: metal production in the midlands, for example, and coal mining in the north-east.two illustrations of 18t
