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.
Q: Passage: Fortunately for Joseon, instead of invading them immediately, from late 1633 to mid 1635, Later Jin set out to conquer nearby Ming and Mongolian territories with particular attention to Chahar Mongol tribe. While this period should have been the opportunity for the Joseon government to strengthen their defense, political situations stood in their way. First, a Ming envoy, Lu Weining visited Joseon in June 1634 to preside at the installation ceremony of their crown prince. Unfortunately for Joseon, the envoy requested excessive amount of bribe in return for the ceremony. In addition, quite a few merchants who attended the envoy sought to make a huge fortune by forcing unfair trades upon their Joseon counterparts. This envoy visit eventually cost Joseon more than 100,000 taels of silver. King Injo, who had successfully accomplished installations of both his parents and son with help from Ming, now attempted to relocate the memorial tablet of his late father into the Jongmyo Shrine. As his father has never actually ruled as the king, this attempt met with severe opposition from government officials, which lasted until early 1635. Adding to this, the mausoleum of King Seonjo was accidentally damaged in March 1635 and the political debate about its responsibility continued for the next few months. These political gridlocks prohibited Joseon from taking enough measure to prepare for a possible invasion from Later Jin.
A:
How many months after Lu Weining visited Joseon to preside at the installation ceremony of the crown prince was the mausoleum of King Seonjo accidentally damaged?
