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.

Question: Passage: The Browns hosted the Pittsburgh Steelers, who were coming off a loss against the Cowboys. The Steelers defeated the Browns 24-9, dropping the Browns to 0-11. With the loss, the Browns were mathematically eliminated from postseason contention for the 14th consecutive season. For the second consecutive season, they were the first NFL team to be mathematically eliminated from contention. The Browns have now gone 24 consecutive seasons without winning a division title, extending the longest active streak in the NFL. They also extended their current franchise record for most consecutive games lost to 14 games. The team is also the first team to start 0-11 since the 2011 Indianapolis Colts.

Answer: How many points did the Browns lose by?


Question: Passage: In 1916 Romania entered World War I on the side of the Allies. In doing so, Romania's goal was to unite all the territories with a Romanian national majority into one state. In the Treaty of Bucharest , terms for Romania's acquisition of territories within Austria-Hungary were stipulated. In 1918, after the October Revolution, the Bolsheviks signed a separate peace with the Central Powers in the Treaty of Brest-Litovsk. Romania was alone on the Eastern Front, a situation that far surpassed its military capabilities. Therefore, on 7 May 1918, Romania sued for peace. The prime minister of Romania, Alexandru Marghiloman, signed the Treaty of Bucharest  with the Central Powers. However, this treaty was never signed by King Ferdinand of Romania. At the end of 1918 Romania's situation was dire. She was suffering from the consequences of punitive war reparations. Dobruja was under Bulgarian occupation. The German army under the command of Field Marshal August von Mackensen was retreating through Romania. The bulk of the Romanian army was demobilized, leaving only four full-strength divisions. A further eight divisions were left in a reserve status. The four battle-ready divisions were used to keep order and protect Basarabia from possible hostile actions of the Soviet Union. On 10 November 1918, taking advantage of the Central Powers' precarious situation, Romania re-entered the war on the side of the Allied forces, with similar objectives to those of 1916. King Ferdinand called for the mobilization of the Romanian army and ordered it to attack by crossing the Carpathian Mountains into Transylvania. The end of World War I that soon followed did not bring an end to  fighting for the Romanian army. Its action continued into 1918 and 1919 in the Hungarian-Romanian war.

Answer:
How many months after suing for peace did Romania rejoin the war?
