What percent of one’s daily caloric intake should come from carbohydrates?
NISA [10]
This answer will vary a lot, depending on who you will ask. If you're asking proponents of the LCHF (low carbs, high fat) diet, they would say you should reduce your intake of carbohydrates down to around 10 to 20 percent, making either A or C your desired answer.

If you would ask people who propose the current nutritional guidelines as the best way of eating, the amount of caloric intake that should come from carbs according to them would be more in the range of around 40%, making B the correct answer.

There isn't really any clear cut answer here.

---------------- is the finest material can be blasted more than 20 kilometers into the atmosphere and carried much farther down
Ghella [55]

Pyroclastic materials are classified according to their size, measured in milli meters: dust (less than 0.6 mm [0.02 inch]), ash (fragments between 0.6 and 2 mm [0.02 to 0.08 inch]), cinders (fragments between 2 and 64 mm [0.08 and 2.5 inches], also known as lapilli), blocks (angular fragments greater than 64 mm), and bombs (rounded fragments greater than 64 mm).

The fluid nature of a pyroclastic flow is maintained by the turbulence of its internal gases. Both the incandescent pyroclastic particles and the rolling clouds of dust that rise above them actively liberate more gas. The expansion of these gases accounts for the nearly frictionless character of the flow as well as its great mobility and destructive power.

Pyroclastic flow, in a volcanic eruption, a fluidized mixture of hot rock fragments, hot gases, and entrapped air that moves at high speed in thick, gray-to-black, turbulent clouds that hug the ground. The temperature of the volcanic gases can reach about 600 to 700 °C (1,100 to 1,300 °F). The velocity of a flow often exceeds 100 km (60 miles) per hour and may attain speeds as great as 160 km (100 miles) per hour.
