TASK DEFINITION: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
PROBLEM: Passage: Taksin's first attempt at reunification—an expedition to Phitsanulok in May 1768—was unsuccessful. He captured Phimai at the end of 1768, and was crowned monarch in December 1768. By late 1769, he had defeated Nakhon Si Thammarat. In mid-1770, he finally defeated Phitsanulok, and became the sole ruler of Siam.

SOLUTION: How many months after Taksin's first attempt at reunification was he crowned monarch?

PROBLEM: Passage: The Saints began their season with a Week 1 duel with the Detroit Lions. New Orleans would get off to a fast start in the first quarter as quarterback Drew Brees completed a 9-yard touchdown pass to wide receiver Marques Colston and a 39-yard touchdown pass to wide receiver Robert Meachem. The Lions would answer with kicker Jason Hanson getting a 47-yard field goal. In the second quarter, Detroit came closer as running back Kevin Smith got a 4-yard touchdown run. The Saints would reply with Brees completing a 1-yard and a 15-yard touchdown pass to tight end Jeremy Shockey. The Lions tried to catch up in the third quarter as quarterback Matthew Stafford got a 1-yard touchdown run, yet New Orleans answered with kicker John Carney making a 39-yard field goal. Detroit would respond with Hanson nailing a 24-yard field goal, while the Saints kept pounding away as Brees completed a 58-yard touchdown pass to wide receiver Devery Henderson. The Lions would close out the period with safety Louis Delmas returning a fumble 65 yards for a touchdown. In the fourth quarter, New Orleans closed out the game as Brees completed a 13-yard touchdown pass to fullback Heath Evans. With the win, not only did the Saints begin their season at 1-0, but Brees (26-of-34, 358 yards, 6 TDs, 1 INT) became the very first quarterback to throw 6 TD passes in an opening day game, as well as tying Billy Kilmer's franchise record for touchdown passes in a game.

SOLUTION: How long was the longest touchdown?

PROBLEM: Passage: The northern section of Army Group South faced the Southwestern Front, which had the largest concentration of Soviet forces, and the southern section faced the Southern Front. In addition, the Pripyat Marshes and the Carpathian Mountains posed a serious challenge to the army groups northern and southern sections respectively. On 22 June, only the northern section of Army Group South attacked, but the terrain impeded their assault, giving the Soviet defenders ample time to react. The German 1st Panzer Group and 6th Army attacked and broke through the Soviet 5th Army. Starting on the night of 23 June, the Soviet 22nd and 15th Mechanized Corps attacked the flanks of the 1st Panzer Group from north and south respectively. Although intended to be concerted, Soviet tank units were sent in piecemeal due to poor coordination. The 22nd Mechanized Corp ran into the 1st Panzer Armys III Motorized Corps and was decimated, and its commander killed. The 1st Panzer Group bypassed much of the 15th Mechanized Corps, which engaged the German 6th Armys 297th Infantry Division, where it was defeated by antitank fire and Luftwaffe attacks. On 26 June, the Soviets launched another counterattack on the 1st Panzer Group from north and south simultaneously with the 9th, 19th and 8th Mechanized Corps, which altogether fielded 1649 tanks, and supported by the remnants of the 15th Mechanized Corps. The battle lasted for four days, ending in the defeat of the Soviet tank units. On 30 June Stavka ordered the remaining forces of the Southwestern Front to withdraw to the Stalin Line, where it would defend the approaches to Kiev.

SOLUTION:
How many Mechanized Corps groups fought on June 26th?
