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.

Passage: Following a preliminary bombardment, the battle for Cebu City began on March 26, 1945, when the Allies launched Operation Victor II. Staging out of Leyte, where they had conducted rehearsal landings two days earlier, a large flotilla of cruisers and destroyers from the United States Seventh Fleet's Task Force 74 escorted the Cebu Attack Group to the island. Under the leadership of Major General William H. Arnold, the forces assigned to the operation consisted of the Americal Division's 132nd and 182nd Infantry Regiments, totaling about 5,000 men, were landed on Cebu island at Talisay Beach, 4 miles southwest of Cebu City. The 182nd came ashore southwest of the city, while the 132nd landed at a wide gravel beach to the northeast opposite a palm grove. Meeting no Japanese opposition, the U.S. forces nevertheless suffered heavily from mines and booby traps as they crossed the beach.
Question: When were the rehearsal landings?

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/km) including the airport. There were 285,797 housing units at an average density of 1,751 per square mile (676/km). 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?

Passage: Mantua is the ancestral city where the male line of the Gonzaga dynasty ruled, first as marquesses, then after 1540 as dukes, in vassalage to the Holy Roman Empire. Monferrato was a duchy since 1574 on the eastern side of Piedmont, and an Imperial fief since the eleventh or twelfth century. The Gonzagas had enlarged their realm with Monferrato after receiving it in dowry from the wife of duke Frederick II Gonzaga. On 22 September 1612, Francis IV, Duke of Mantua and Monferrato died at the age of 26. His death occurred only a couple of months after the death of his father Vincent I, Duke of Mantua. He left only a three-year-old daughter, Maria of Mantua. Francis IV also had two younger brothers who, both being cardinals, could not marry and were thus ineligible to succeed to Mantua's throne. Nonetheless, Francis' two brothers, Ferdinando I and Vincenzo II , eventually did become Dukes of Mantua. Despite marrying, following the resignation of Ferdinando and the expulsion of Vincenzo from the Sacred College of Cardinals, neither produced any legitimate children. A crisis erupted when Vincenzo II died on 26 December 1627 at the age of 33, the same day that his niece Maria Gonzaga's marriage with Charles de Nevers was celebrated. Nevers was the eldest son and heir of Charles, Duke of Nevers, Rethel and Mayenne. Moreover, he was the head of the cadet branch of the House of Gonzaga, and after Vincenzo II, heir male of the Duchy of Mantua.
Question: What year was Maria of Mantua born in?
