Problem: Dutch language:

Next to sound shifts, there are ample examples of suffix differences. Often simple suffix shifts (like switching between -the, -ske, -ke, -je, ...), sometimes the suffixes even depend on quite specific grammar rules for a certain dialect. Again taking West Flemish as an example. In that language, the words "ja" (yes) and "nee" (no) are also conjugated to the (often implicit) subject of the sentence. These separate grammar rules are a lot more difficult to imitate correctly than simple sound shifts, making it easy to recognise people who didn't grow up in a certain region, even decades after they moved.

Which is easier for a non-native speaker to imitate: grammar rules or sound shifts?

A: sound shifts

Problem: One of the league's early success stories was the Detroit Drive. A primary team for some of the AFL's most highly regarded players, including George LaFrance and Gary and Alvin Rettig, as well as being a second career chance for quarterback Art Schlichter, the Drive regularly played before sold out crowds at Joe Louis Arena, and went to the ArenaBowl every year of their existence (19881993). The AFL's first dynasty came to an end when their owner, Mike Ilitch (who also owned Little Caesars Pizza and the Detroit Red Wings) bought the Detroit Tigers baseball team and sold the AFL team.
In what year did the Drive go to their first Arena Bowl?

Answer: 1988

At the end of the war, the victorious powers sought to divide up the Ottoman Empire. Signed between the Allied and Associated Powers and Ottoman Empire at Sevres on 10 August 1920, the Treaty of Sevres promised to maintain the existence of the Armenian republic and to attach the former territories of Ottoman Armenia to it. Because the new borders of Armenia were to be drawn by United States President Woodrow Wilson, Ottoman Armenia was also referred to as "Wilsonian Armenia." In addition, just days prior, on 5 August 1920, Mihran Damadian of the Armenian National Union, the de facto Armenian administration in Cilicia, declared the independence of Cilicia as an Armenian autonomous republic under French protectorate.
When was the Treaty of Sevres signed?
A: 10 August 1920

Context and question: The "yo yo" in the opinion polls continued into 1992, though after November 1990 any Labour lead in the polls was rarely sufficient for a majority. Major resisted Kinnock's calls for a general election throughout 1991. Kinnock campaigned on the theme "It's Time for a Change", urging voters to elect a new government after more than a decade of unbroken Conservative rule. However, the Conservatives themselves had undergone a dramatic change in the change of leader from Thatcher to Major, at least in terms of style if not substance. From the outset, it was clearly a well-received change, as Labour's 14-point lead in the November 1990 "Poll of Polls" was replaced by an 8% Tory lead a month later.
What did the percentage fall to?
Answer: 8%

The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.
When did amphibious tetrapods become prominent?
A:
