Problem: I know that the answer to the question "When can deciding whether a dialect of language is difficult?" is in "The most common, and most purely linguistic, criterion is that of mutual intelligibility: two varieties are said to be dialects of the same language if being a speaker of one variety confers sufficient knowledge to understand and be understood by a speaker of the other; otherwise, they are said to be different languages. However, this definition becomes problematic in the case of dialect continua, in which it may be the case that dialect B is mutually intelligible with both dialect A and dialect C but dialects A and C are not mutually intelligible with each other. In this case the criterion of mutual intelligibility makes it impossible to decide whether A and C are dialects of the same language or not. Cases may also arise in which a speaker of dialect X can understand a speaker of dialect Y, but not vice versa; the mutual intelligibility criterion flounders here as well.". Can you tell me what it is?

A: in which it may be the case that dialect B is mutually intelligible with both dialect A and dialect C but dialects A and C are not mutually intelligible with each other

Problem: I know that the answer to the question "What would imply that a tree was growing during cold seasons?" is in "If a heavy piece of pine is compared with a lightweight piece it will be seen at once that the heavier one contains a larger proportion of latewood than the other, and is therefore showing more clearly demarcated growth rings. In white pines there is not much contrast between the different parts of the ring, and as a result the wood is very uniform in texture and is easy to work. In hard pines, on the other hand, the latewood is very dense and is deep-colored, presenting a very decided contrast to the soft, straw-colored earlywood.". Can you tell me what it is?

A: a larger proportion of latewood

Problem: I know that the answer to the question "What puzzle is about things that have various numbers of sides?" is in "The Times's main supplement, every day, is the times2, featuring various lifestyle columns. It was discontinued on 1 March 2010 but reintroduced on 11 October 2010 after negative feedback. Its regular features include a puzzles section called Mind Games. Its previous incarnation began on 5 September 2005, before which it was called T2 and previously Times 2. Regular features include columns by a different columnist each weekday. There was a column by Marcus du Sautoy each Wednesday, for example. The back pages are devoted to puzzles and contain sudoku, "Killer Sudoku", "KenKen", word polygon puzzles, and a crossword simpler and more concise than the main "Times Crossword".". Can you tell me what it is?

A: polygon

Problem: I know that the answer to the question "Which country claimed by ISIL was NOT bombed by the coalition?" is in "With the emergence of ISIL and its capture of large areas of Iraq and Syria, a number of crises resulted that sparked international attention. ISIL had perpetrated sectarian killings and war crimes in both Iraq and Syria. Gains made in the Iraq war were rolled back as Iraqi army units abandoned their posts. Cities were taken over by the terrorist group which enforced its brand of Sharia law. The kidnapping and decapitation of numerous Western journalists and aid-workers also garnered interest and outrage among Western powers. The US intervened with airstrikes in Iraq over ISIL held territories and assets in August, and in September a coalition of US and Middle Eastern powers initiated a bombing campaign in Syria aimed at degrading and destroying ISIL and Al-Nusra-held territory.". Can you tell me what it is?

A:
Iraq
