TASK DEFINITION: In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.
PROBLEM: Passage: A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer.

SOLUTION: How many thin films need to be stacked to have a special label applied to them?

PROBLEM: Passage: In 2009 it was announced that the feature film Testament of Youth was in development by BBC Films and Heyday Films producer David Heyman, and was to be directed by James Kent. This had the support of the Vera Brittain Estate, Brittain's daughter Shirley Williams, and Brittain's biographer Mark Bostridge who is acting as consultant. Saoirse Ronan was cast to play Brittain in 2012 but was replaced in December 2013 when it was announced that Alicia Vikander would play Vera Brittain in the film which was released in late 2014 as part of the First World War commemorations. On 4 February 2014 Kit Harington joined the cast to play the role of Brittain's fiancé Roland Leighton. On 13 February 2014, Colin Morgan, Taron Egerton, and Alexandra Roach were announced to have joined the film's cast. An ensemble cast was later confirmed as filming began, including Dominic West, Emily Watson, Joanna Scanlan, Hayley Atwell, Jonathan Bailey and Anna Chancellor. It substituted Merton College, Oxford in the scenes showing Brittain's time as a student at Somerville College, arguing that filming in Somerville itself would been too difficult in light of the new buildings constructed there since the film's time period.

SOLUTION: Why was Saoirse Ronan replaced by Alicia Vikander?

PROBLEM: Passage: In 2001 Sinaltrainal v. Coca-Cola was filed in the Florida Third District Court of Appeal, demanding a monetary compensation for $500 million for the deaths of three workers, members of the National Union for Food Industry Workers who worked in the Coca-Cola Bebidas y Alimentos plant in Carepa in northern Colombia. The lawsuit was brought by the Colombian trade union Sinaltrainal (National Union of Food Workers) and alleged that Panamco, a Colombian Coca-Cola bottling company, assisted paramilitaries in murdering several union members. Even though the alleged human rights violation occurred in Colombia, the union attempted to use the Alien Tort Claims Act (ATCA) to bring the case into a U.S. district court. The ATCA grants U.S. courts jurisdiction in any dispute where it is alleged that a tort has been committed in violation of the "law of nations" or a treaty of the United States. The plaintiffs also alleged violations of the Torture Victims Protection Act (TVPA).

SOLUTION:
How many times was the ATCA used in 2001?
