Problem: It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.
What are two organisms that have more non-repetitive than repetitive DNA?

Answer: C. elegans and fruit fly

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the example above, the identity and the rotations constitute a subgroup R = {id, r1, r2, r3}, highlighted in red in the group table above: any two rotations composed are still a rotation, and a rotation can be undone by (i.e. is inverse to) the complementary rotations 270 for 90, 180 for 180, and 90 for 270 (note that rotation in the opposite direction is not defined). The subgroup test is a necessary and sufficient condition for a subset H of a group G to be a subgroup: it is sufficient to check that g1h H for all elements g, h H. Knowing the subgroups is important in understanding the group as a whole.d["]
270 for 180 is an example of what kind of rotation?
A: unanswerable

Context and question: Besides the schism, the western church was riven by theological controversies, some of which turned into heresies. John Wycliffe (d. 1384), an English theologian, was condemned as a heretic in 1415 for teaching that the laity should have access to the text of the Bible as well as for holding views on the Eucharist that were contrary to church doctrine. Wycliffe's teachings influenced two of the major heretical movements of the later Middle Ages: Lollardy in England and Hussitism in Bohemia. The Bohemian movement initiated with the teaching of Jan Hus, who was burned at the stake in 1415 after being condemned as a heretic by the Council of Constance. The Hussite church, although the target of a crusade, survived beyond the Middle Ages. Other heresies were manufactured, such as the accusations against the Knights Templar that resulted in their suppression in 1312 and the division of their great wealth between the French King Philip IV (r. 12851314) and the Hospitallers.
Of what nationality was John Wycliffe?
Answer: English

Question: The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.
Is there an answer to this question: How much was 1 troy ounce of gold worth?

Answer: $20.67
