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.

Passage: Since the takeover in 2011, NEEP Roma Holding S.p.A. has owned all shares Sensi previously hold. NEEP, itself a joint venture, was held by DiBenedetto AS Roma LLC (later renamed to AS Roma SPV, LLC) and Unicredit in 60–40 ratio from 2011 to 2013, which the former had four real person shareholders in equal ratio, led by future Roma president Thomas R. DiBenedetto (2011–12). The takeover also activated a mandatory bid of shares from the general public, however not all minority shareholders were willing to sell their shares. The mandatory bid meant NEEP held 78.038% of shares of AS Roma (increased from 67.1% of the Sensi). On 1 August 2013, the president of Roma as well as one of the four American shareholders of AS Roma SPV, LLC, James Pallotta, bought an additional 9% shares of NEEP Roma Holding from Unicredit (through Raptor Holdco LLC), as the bank was not willing to fully participate in the capital increase of NEEP from €120,000 to €160,008,905 (excluding share premium). On 4 April 2014 Starwood Capital Group also became the fifth shareholder of AS Roma SPV, as well as forming a strategic partnership with AS Roma SpA to develop real estate around the new stadium. The private investment firm was represented by Zsolt Kohalmi in AS Roma SPV, who was appointed on 4 April as a partner and head of European acquisitions of the firm. On 11 August 2014, UniCredit sold the remain shares on NEEP (of 31%) for €33 million which meant AS Roma SPV LLC (91%) and Raptor Holdco LLC (9%) were the sole intermediate holding company of AS Roma SpA.
How many months after Zsolt Kohalmi was appointed partner and head of European acquisitions did UniCrdit sell the remaing shares on NEEP?

Passage: The road building programme was also expanded, with capital expenditure increased to 8% of GDP, "the highest level achieved by any post-war government".
