Problem: Zinc:

Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 C. Above 210 C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 C) and boiling points (907 C). Its melting point is the lowest of all the transition metals aside from mercury and cadmium.

In it's pre commercial state, what color is zinc?

A: bluish-white

Problem: During the year following that contract, with Dodsley, Burke founded the influential Annual Register, a publication in which various authors evaluated the international political events of the previous year. The extent to which Burke contributed to the Annual Register is unclear: in his biography of Burke, Robert Murray quotes the Register as evidence of Burke's opinions, yet Philip Magnus in his biography does not cite it directly as a reference. Burke remained the chief editor of the publication until at least 1789 and there is no evidence that any other writer contributed to it before 1766.
Dodsley was the only writer for the register until what year?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
When the act is assented to by the sovereign in person, or by empowered Royal Commissioners, royal assent is considered given at the moment when the assent is declared in the presence of both houses jointly assembled. When the procedure created by the Royal Assent Act 1967 is followed, assent is considered granted when the presiding officers of both houses, having received the letters patent from the king or queen signifying the assent, have notified their respective house of the grant of royal assent. Thus, if each presiding officer makes the announcement at a different time (for instance because one house is not sitting on a certain date), assent is regarded as effective when the second announcement is made. This is important because, under British Law, unless there is any provision to the contrary, an act takes effect on the date on which it receives royal assent and that date is not regarded as being the date when the letters patent are signed, or when they are delivered to the presiding officers of each house, but the date on which both houses have been formally acquainted of the assent.
Under American law, an act takes effect when?
A: unanswerable

Context and question: Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of 7000100794000000000♠️1.00794 u, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.[note 1] Non-remnant stars are mainly composed of hydrogen in its plasma state. The most common isotope of hydrogen, termed protium (name rarely used, symbol 1H), has one proton and no neutrons.
What is hydrogens chemical symbol?
Answer: H

Question: Pain is usually transitory, lasting only until the noxious stimulus is removed or the underlying damage or pathology has healed, but some painful conditions, such as rheumatoid arthritis, peripheral neuropathy, cancer and idiopathic pain, may persist for years. Pain that lasts a long time is called chronic or persistent, and pain that resolves quickly is called acute. Traditionally, the distinction between acute and chronic pain has relied upon an arbitrary interval of time from onset; the two most commonly used markers being 3 months and 6 months since the onset of pain, though some theorists and researchers have placed the transition from acute to chronic pain at 12 months.:93 Others apply acute to pain that lasts less than 30 days, chronic to pain of more than six months' duration, and subacute to pain that lasts from one to six months. A popular alternative definition of chronic pain, involving no arbitrarily fixed durations, is "pain that extends beyond the expected period of healing". Chronic pain may be classified as cancer pain or else as benign.
Is there an answer to this question: How long does pain tend to last?

Answer: only until the noxious stimulus is removed

Question: About half of the population depends on agriculture (largely subsistence agriculture) for its livelihood, but Namibia must still import some of its food. Although per capita GDP is five times the per capita GDP of Africa's poorest countries, the majority of Namibia's people live in rural areas and exist on a subsistence way of life. Namibia has one of the highest rates of income inequality in the world, due in part to the fact that there is an urban economy and a more rural cash-less economy. The inequality figures thus take into account people who do not actually rely on the formal economy for their survival. Although arable land accounts for only 1% of Namibia, nearly half of the population is employed in agriculture.
Is there an answer to this question: How much of the population depends on agriculture?

Answer:
half
