Detailed Instructions: 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: In November 2014, Vice News launched its French-language version. In October 2015 Vice hired Josh Tyrangiel to run a daily Vice News show for HBO. Tyrangiel had recently left Bloomberg, where he was reported to be "a divisive figure who was both admired and despised during his six years there." Tyrangiel named Ryan McCarthy, formerly an assistant editor of The New York Times, as editor-in-chief of Vice News. In May 2016, it was announced that Tyrangiel had also been given control of the weekly Vice on HBO show as well as Vice News. As the announcement was made, Tyrangiel promptly laid off much of the news staff. In an interview given the previous week, Vice Media founder Shane Smith called Tyrangiel "a murderer," foretelling a "bloodbath" in digital media. On May 24, 2016, a change in leadership at Vice News resulted in the laying off of some 20 editorial and production staff members. That June, Tyrangiel touted various new hires he had brought aboard as part of his team. In December 2016, it was announced that Vice News had entered into a partnership with The Guardian newspaper that will include Guardian journalists working at Vice's offices in East London and contributing to the two HBO television programs currently on the air. It will also include allowing The Guardian access to Vice's video production skills with content distributed to its millennial-skewed global audience.
A:
How many month's after Tyrangiel's mass layoff did Vice join with the Guardian?
