Problem: Copper:

Copper occurs naturally as native copper and was known to some of the oldest civilizations on record. It has a history of use that is at least 10,000 years old, and estimates of its discovery place it at 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC. There is evidence that gold and meteoric iron (but not iron smelting) were the only metals used by humans before copper. The history of copper metallurgy is thought to have followed the following sequence: 1) cold working of native copper, 2) annealing, 3) smelting, and 4) the lost wax method. In southeastern Anatolia, all four of these metallurgical techniques appears more or less simultaneously at the beginning of the Neolithic c. 7500 BC. However, just as agriculture was independently invented in several parts of the world, copper smelting was invented locally in several different places. It was probably discovered independently in China before 2800 BC, in Central America perhaps around 600 AD, and in West Africa about the 9th or 10th century AD. Investment casting was invented in 45004000 BC in Southeast Asia and carbon dating has established mining at Alderley Edge in Cheshire, UK at 2280 to 1890 BC. Otzi the Iceman, a male dated from 33003200 BC, was found with an axe with a copper head 99.7% pure; high levels of arsenic in his hair suggest his involvement in copper smelting. Experience with copper has assisted the development of other metals; in particular, copper smelting led to the discovery of iron smelting. Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6000 and 3000 BC. Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC.[citation needed]

When did natural bronze stop being used by the general public?

Problem: Laws dating from 17th-century colonial America defined children of African slave mothers as taking the status of their mothers, and born into slavery regardless of the race or status of the father, under partus sequitur ventrem. The association of slavery with a "race" led to slavery as a racial caste. But, most families of free people of color formed in Virginia before the American Revolution were the descendants of unions between white women and African men, who frequently worked and lived together in the looser conditions of the early colonial period. While interracial marriage was later prohibited, white men frequently took sexual advantage of slave women, and numerous generations of multiracial children were born. By the late 1800s it had become common among African Americans to use passing to gain educational opportunities as did the first African-American graduate of Vassar College Anita Florence Hemmings. Some 19th-century categorization schemes defined people by proportion of African ancestry: a person whose parents were black and white was classified as mulatto, with one black grandparent and three white as quadroon, and with one black great-grandparent and the remainder white as octoroon. The latter categories remained within an overall black or colored category, but before the Civil War, in Virginia and some other states, a person of one-eighth or less black ancestry was legally white. Some members of these categories passed temporarily or permanently as white.
What is the rule that allows children with white fathers to be slaves?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The foregoing trees, shrubs and herbs are also more widely distributed in less rich mesic forests that generally occupy coves, stream valleys and flood plains throughout the southern and central Appalachians at low and intermediate elevations. In the northern Appalachians and at higher elevations of the central and southern Appalachians these diverse mesic forests give way to less diverse "northern hardwoods" with canopies dominated only by American beech, sugar maple, American basswood (Tilia americana) and yellow birch and with far fewer species of shrubs and herbs.
Which part of the appalachians have a significant number of shrubs at high elevations?
A: unanswerable

Context and question: Panels are individual images containing a segment of action, often surrounded by a border. Prime moments in a narrative are broken down into panels via a process called encapsulation. The reader puts the pieces together via the process of closure by using background knowledge and an understanding of panel relations to combine panels mentally into events. The size, shape, and arrangement of panels each affect the timing and pacing of the narrative. The contents of a panel may be asynchronous, with events depicted in the same image not necessarily occurring at the same time.
What are the multiple images with action called in comics?
Answer: unanswerable

Question: All Latin characters required by Peh-oe-ji can be represented using Unicode (or the corresponding ISO/IEC 10646: Universal Character Set), using precomposed or combining (diacritics) characters. Prior to June 2004, the vowel akin to but more open than o, written with a dot above right, was not encoded. The usual workaround was to use the (stand-alone; spacing) character Interpunct (U+00B7, ) or less commonly the combining character dot above (U+0307). As these are far from ideal, since 1997 proposals have been submitted to the ISO/IEC working group in charge of ISO/IEC 10646namely, ISO/IEC JTC1/SC2/WG2to encode a new combining character dot above right. This is now officially assigned to U+0358 (see documents N1593, N2507, N2628, N2699, and N2713). Font support is expected to follow.
Is there an answer to this question: What is expected to follow using diacritics?

Answer: unanswerable

Problem: Israel:

The names Land of Israel and Children of Israel have historically been used to refer to the biblical Kingdom of Israel and the entire Jewish people respectively. The name "Israel" (Standard Yisrael, Israil; Septuagint Greek: Israel; 'El(God) persists/rules' though, after Hosea 12:4 often interpreted as "struggle with God") in these phrases refers to the patriarch Jacob who, according to the Hebrew Bible, was given the name after he successfully wrestled with the angel of the Lord. Jacob's twelve sons became the ancestors of the Israelites, also known as the Twelve Tribes of Israel or Children of Israel. Jacob and his sons had lived in Canaan but were forced by famine to go into Egypt for four generations, lasting 430 years, until Moses, a great-great grandson of Jacob, led the Israelites back into Canaan during the "Exodus". The earliest known archaeological artifact to mention the word "Israel" is the Merneptah Stele of ancient Egypt (dated to the late 13th century BCE).

Who led the Israelites back into Canaan during the "Exodus?"
