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.

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.

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

Passage: A second battalion was raised in 1804 to increase the strength of the regiment. The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807. It then embarked for Portugal in May 1808 for service under General Sir Arthur Wellesley in the Peninsular War and saw action at the Battle of Rolica in August 1808 and the Battle of Vimeiro later that month. In January 1809 the battalion took part in the Battle of Corunna, carrying out successive bayonet charges to keep the French at bay to which General Sir John Moore shouted "Well done, 50th! Well done, my Majors!". The battalion was subsequently evacuated from the Peninsula. Both battalions then embarked from the Downs in July 1809 and saw action in the disastrous Walcheren Campaign. It was the last regiment to leave Holland in December 1809.

Passage: In October 2004, the Midland Group announced its intention to enter Formula One motor racing in 2006, with plans to use a car built by the Italian manufacturer Dallara In January 2005 the group changed plans by purchasing the Jordan Grand Prix team. They kept the yellow-liveried EJ15 cars and declared 2005 to be a year of learning. Under the name Midland F1 Racing, the team made its debut with a brand-new car and livery at the start of the 2006 Formula One season. With this team, Shnaider declared his intention to bring the first Russian driver into the sport, a feat not achieved until Vitaly Petrov's entrance into F1 with Renault, three years after Schnaider sold the team. On 9 September 2006, the team was sold to Spyker Cars for $106.6 million. From the beginning of the 2008 season, the team became known as Force India and remained active until 2018, when a group of consortium led by Lawrence Stroll bought the team in 2018 following a financial collapse that forced Force India to be put under administration. The team currently competes under the Racing Point banner.
Link Information: For the 2018 season the team retained the 2017 line up of Sergio Perez and Esteban Ocon Answer: Sergio Perez
What was the person that drove for Force India in their last year of competition?
