PROBLEM: Passage: The Mortlake and Barnes Common ward of the London Borough of Richmond upon Thames has proved highly marginal. In the 2010 local elections local Liberal Democrats lost all three seats to local Conservatives, the latter forming an administration on Richmond Council. This remained the case until the 2018 local elections when the Liberal Democrats regained one of the three seats by a single vote. The Liberal Democrats also regained control of the Council. Richmond Park, the constituency which includes Mortlake, had changed from Liberal Democrat to Conservative in the 2010 general election, was recaptured by the Liberal Democrats in the 2016 by-election, and finally reverted to Conservative MP Zac Goldsmith in the 2017 general election by a margin of only 45 votes. The London Assembly constituency South West, which includes Mortlake, is represented by former local councillor Tony Arbour (Conservative).

PROBLEM: Passage: The next film directed by Lean was The Passionate Friends (1949), an atypical Lean film, but one which marked his first occasion to work with Claude Rains, who played the husband of a woman (Todd) torn between him and an old flame (Howard). The Passionate Friends was the first of three films to feature the actress Ann Todd, who became his third wife. Madeleine (1950), set in Victorian-era Glasgow is about an 1857 cause celebre with Todd's lead character accused of murdering a former lover. "Once more", writes film critic David Thomson "Lean settles on the pressing need for propriety, but not before the film has put its characters and the audience through a wringer of contradictory feelings." The last of the films with Todd, The Sound Barrier (1952), has a screenplay by the playwright Terence Rattigan and was the first of his three films for Sir Alexander Korda's London Films. Hobson's Choice (1954), with Charles Laughton in the lead, was based on the play by Harold Brighouse.

SOLUTION: Answer: none

PROBLEM: Passage: The season featured nine tropical cyclones, of which eight further intensified into tropical storms and six further intensified into hurricanes (including two major hurricanes). Impact throughout the year was widespread. In early July, Hurricane Arthur moved ashore near Cape Lookout, North Carolina, resulting in minor damage and one indirect death. In August, hurricanes Bertha and Cristobal moved across the southwestern Atlantic, causing minimal damage and several fatalities. In September, Tropical Storm Dolly moved ashore the coastline of eastern Mexico, killing one and inflicting unsubstantial damage, while Hurricane Edouard created large swells that impacted the East Coast of the United States and killed two people. In October, hurricanes Fay and Gonzalo moved ashore Bermuda, marking the first time more than one tropical cyclone made landfall on the island in a single season on record. Hanna impacted Central America later that month but caused no damage.
