Input: Consider Input: Question: What date did the Journal publish the report of Theresa May appearing on Eastenders? Passage:On April Fools' Day 2019, TheJournal.ie published a report on Prime Minister Theresa May's scheduled appearance on that night's special live episode of EastEnders, details of which had been leaked by Taoiseach Leo Varadkar overnight. May's purpose was to issue a final plea for unity as Brexit entered a critical stage. The internet publication featured a photograph of May in The Queen Victoria pub, with the caption "Rehearsal shot of hostile locals witnessing May's arrival". It even went so far as to compose fake documents to back up its claim, including a draft script said to have been provided by the BBC to highlight the ever-changing difficulties of keeping up with political events as they rapidly unfolded: "'This is the 416th draft' the source said. 'And her appearance was only confirmed at the start of March. Brexit won't stop f*****g, c*****g changing every two seconds. It's driving the actors mad.'" A short video clip shows actor Adam Woodyatt (who portrays the character of Ian Beale) being comforted by colleague Steve McFadden (who portrays the character Phil Mitchell), as Woodyatt bursts into tears due to the protracted rehearsals. The preliminary script — which, TheJournal.ie reminded readers, was "contingent on what the hell happens in Brexit over the course of today" — had Dot Cotton (played by June Brown) gasping as Theresa May enters the pub. May, having begun her speech, is interrupted by Mick Carter (played by Danny Dyer) who knocks over a pint and a chair in his efforts to have the Prime Minister leave the pub. May departs and perches herself despondently on a park bench, whereupon Kat Slater (played by Jessie Wallace) approaches her with "Alright love? What's getting you down?" May tells Slater she has already blamed everyone — the Irish, the Democratic Unionist Party, the European Union — and is at a loss for who is left for her to find fault with now. Slater advises her to be honest. May finds solace in this, thanks Slater, remarks on the chilliness of the night and Slater hands the Prime Minister her leopard print jacket to put on. May returns to the pub and seemingly converts all the customers bar Dot Cotton, who is promptly ejected onto the street.

Input: Consider Input: Question: Which team had more wins, the Reds or the Pirates? Passage:Holding off fierce competition from the Cincinnati Reds and Pittsburgh Pirates, the Cardinals clinched the division crown as each team won at least 90 games. The Cardinals finished the season with an NL-best 97–65 won–loss record. They opened the playoffs by defeating the Pirates in five games in the NL Division Series (NLDS). Advancing to their third straight National League Championship Series, they defeated the Los Angeles Dodgers in six games for their 19th NL pennant. Rookie Michael Wacha, who had nearly no-hit the Washington Nationals late in September, continued his dominance throughout the postseason as he allowed no runs against the Dodgers in 13 IP, earning the NLCS MVP. It was the second straight NLCS appearance to which manager Mike Matheny guided the Cardinals, who became the first manager to appear in an LCS in his first two seasons. Rookie closer Trevor Rosenthal extended a 20-inning postseason scoreless streak that started in the 2012 NLDS. The Cardinals met the Boston Red Sox in the World Series, only to lose the series in six games.
