This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
question:
Passage: According to the 2010 United States Census, the City and County of Denver contained 600,158 people and 285,797 households. The population density was 3,698 inhabitants per square mile (1,428/km²) including the airport. There were 285,797 housing units at an average density of 1,751 per square mile (676/km²). However, the average density throughout most Denver neighborhoods tends to be higher. Without the 80249 zip code (47.3 sq mi, 8,407 residents) near the airport, the average density increases to around 5,470 per square mile.Age distribution was 22.0% under the age of 18, 10.7% from 18 to 24, 36.1% from 25 to 44, 20.0% from 45 to 64, and 11.3% who were 65 years of age or older. The median age is 33 years. Overall there were 102.1 males for every 100 females, but in 2015 for the category of never-married ages 25 to 34, there were 121.4 males for every 100 females. Due to a skewed sex ratio wherein single men outnumber single women, some protologists have nicknamed the city as Menver.
Question: Which age group populated Denver less, those under the age of 18 or 18 to 44?
answer:
span

Passage: With the tribes to the north and west destroyed, the Iroquois turned their attention southward to the Iroquoian-speaking Susquehannock. 1660 marked the zenith of Iroquois military power, and they were able to use that to their advantage in the decades to follow. The Susquehannock had become allied with the English in the Maryland colony in 1661. The English had grown fearful of the Iroquois and hoped an alliance with Susquehannock would help block the northern tribes' advance on the English colonies. In 1663 the Iroquois sent an army of 800 warriors into the Susquehannock territory. They repulsed the army, but the invasion prompted the colony of Maryland to declare war on the Iroquois. By supplying Susquehannock forts with artillery, the English in Maryland changed the balance of power away from the Iroquois. The Susquehannock took the upper hand and began to invade Iroquois territory, where they caused significant damage. This warfare continued intermittently for 11 years. In 1674 the English in Maryland changed their Indian Policy and negotiated peace with the Iroquois. They terminated their alliance with the Susquehannock. In 1675 the militias of Virginia and Maryland captured and executed the chiefs of the Susquehannock, whose growing power they feared. The Iroquois made quick work of the rest of the nation. They drove the warriors from traditional territory and absorbed the survivors in 1677. During the course of this conflict, in 1670 the Iroquois also drove the Siouan-speaking Mannahoac tribe out of the northern Virginia Piedmont region. The Iroquois claimed the land by right of conquest as a hunting ground. The English acknowledged this claim in 1674 and again in 1684. They acquired the land from the Iroquois by a 1722 treaty.
Question: How many years after the Iroquois military power reached its zenith, did the militias of Virginia and Maryland execute the chiefs of the Susquehannock?
answer:
number

Passage: On 2 May, the German capital city, Berlin, fell to the Red Army. On 8 May 1945, the Germans surrendered unconditionally and the war in Europe officially ended. The Italians had quit the war in 1943, the Bulgarians in 1944, and the Hungarians earlier in 1945. Despite the German capitulation, however, sporadic fighting still took place in Yugoslavia. On 7 May, Zagreb was evacuated, on 9 May, Maribor and Ljubljana were captured by the Partisans, and General Alexander Löhr, Commander-in-Chief of Army Group E was forced to sign the total surrender of the forces under his command at Topolšica, near Velenje, Slovenia, on Wednesday 9 May 1945. Only the Croatian and other anti-Partisan forces remained. From 10 to 15 May, the Yugoslav Partisans continued to face resistance from Croatian, and other anti-Partisan forces throughout the rest of Croatia and Slovenia. The Battle of Poljana, the last battle of World War II in Europe, started on 14 May, ending on 15 May 1945 at Poljana, near Prevalje in Slovenia.
