Problem: Please answer a question about the following article about Wood:
In ring-porous species, such as ash, black locust, catalpa, chestnut, elm, hickory, mulberry, and oak, the larger vessels or pores (as cross sections of vessels are called) are localised in the part of the growth ring formed in spring, thus forming a region of more or less open and porous tissue. The rest of the ring, produced in summer, is made up of smaller vessels and a much greater proportion of wood fibers. These fibers are the elements which give strength and toughness to wood, while the vessels are a source of weakness.[citation needed]
What fibers does the summer's section of growth-ring have more of?
A: wood fibers
Problem: Please answer a question about the following article about Muammar Gaddafi:
The son of an impoverished Bedouin goat herder, Gaddafi became involved in politics while at school in Sabha, subsequently enrolling in the Royal Military Academy, Benghazi. Founding a revolutionary cell within the military, in 1969 they seized power from the absolute monarchy of King Idris in a bloodless coup. Becoming Chairman of the governing Revolutionary Command Council (RCC), Gaddafi abolished the monarchy and proclaimed the Republic. Ruling by decree, he implemented measures to remove what he viewed as foreign imperialist influence from Libya, and strengthened ties to Arab nationalist governments. Intent on pushing Libya towards "Islamic socialism", he introduced sharia as the basis for the legal system and nationalized the oil industry, using the increased revenues to bolster the military, implement social programs and fund revolutionary militants across the world. In 1973 he initiated a "Popular Revolution" with the formation of General People's Committees (GPCs), purported to be a system of direct democracy, but retained personal control over major decisions. He outlined his Third International Theory that year, publishing these ideas in The Green Book.
Describe the Popular Revolution.
A: formation of General People's Committees (GPCs), purported to be a system of direct democracy, but retained personal control over major decisions
Problem: Please answer a question about the following article about Nutrition:
The macronutrients are carbohydrates, fats, protein, and water. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories (often called "Calories" and written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons.
What other significant aspect do macronutrients provide other than energy?
A: structural material
Problem: Please answer a question about the following article about Gothic architecture:
On the exterior, the verticality is emphasised in a major way by the towers and spires and in a lesser way by strongly projecting vertical buttresses, by narrow half-columns called attached shafts which often pass through several storeys of the building, by long narrow windows, vertical mouldings around doors and figurative sculpture which emphasises the vertical and is often attenuated. The roofline, gable ends, buttresses and other parts of the building are often terminated by small pinnacles, Milan Cathedral being an extreme example in the use of this form of decoration.
Which cathedral demonstrates a drastic example of termination with small pinnacles?
A:
Milan Cathedral
