Problem: Christian:

As of the early 21st century, Christianity has approximately 2.4 billion adherents. The faith represents about a third of the world's population and is the largest religion in the world. Christians have composed about 33 percent of the world's population for around 100 years. The largest Christian denomination is the Roman Catholic Church, with 1.17 billion adherents, representing half of all Christians.

Problem: Spielberg next directed the historical drama film Lincoln, starring Daniel Day-Lewis as United States President Abraham Lincoln and Sally Field as Mary Todd Lincoln. Based on Doris Kearns Goodwin's bestseller Team of Rivals: The Political Genius of Abraham Lincoln, the film covered the final four months of Lincoln's life. Written by Tony Kushner, the film was shot in Richmond, Virginia, in late 2011, and was released in the United States by Disney in November 2012. The film's international distribution was handled by 20th Century Fox. Upon release, Lincoln received widespread critical acclaim, and was nominated for twelve Academy Awards (the most of any film that year) including Best Picture and Best Director for Spielberg. It won the award for Best Production Design and Day-Lewis won the Academy Award for Best Actor for his portrayal of Lincoln, becoming the first three time winner in that category as well as the first to win for a performance directed by Spielberg.
In what year did Team of Rivals: The Political Genius of Abraham Lincoln get released?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Internet service providers in many countries are legally required (e.g., via Communications Assistance for Law Enforcement Act (CALEA) in the U.S.) to allow law enforcement agencies to monitor some or all of the information transmitted by the ISP. Furthermore, in some countries ISPs are subject to monitoring by intelligence agencies. In the U.S., a controversial National Security Agency program known as PRISM provides for broad monitoring of Internet users traffic and has raised concerns about potential violation of the privacy protections in the Fourth Amendment to the United States Constitution. Modern ISPs integrate a wide array of surveillance and packet sniffing equipment into their networks, which then feeds the data to law-enforcement/intelligence networks (such as DCSNet in the United States, or SORM in Russia) allowing monitoring of Internet traffic in real time.
What do many people say violates the First Amendment?
A: unanswerable

Context and question: where a single prime denotes the real part and a double prime the imaginary part, Z() is the complex impedance with the dielectric present, Ccmplx() is the so-called complex capacitance with the dielectric present, and C0 is the capacitance without the dielectric. (Measurement "without the dielectric" in principle means measurement in free space, an unattainable goal inasmuch as even the quantum vacuum is predicted to exhibit nonideal behavior, such as dichroism. For practical purposes, when measurement errors are taken into account, often a measurement in terrestrial vacuum, or simply a calculation of C0, is sufficiently accurate.)
How is the non-complex impedance with dielectric represented mathematically?
Answer: unanswerable

Question: By 1954, Olympic Games apparatus and events for both men and women had been standardized in modern format, and uniform grading structures (including a point system from 1 to 15) had been agreed upon. At this time, Soviet gymnasts astounded the world with highly disciplined and difficult performances, setting a precedent that continues. The new medium of television has helped publicize and initiate a modern age of gymnastics. Both men's and women's gymnastics now attract considerable international interest, and excellent gymnasts can be found on every continent. Nadia Comaneci received the first perfect score, at the 1976 Summer Olympics held in Montreal, Canada. She was coached in Romania by coach, (Hungarian ethnicity), Bela Karolyi. Comaneci scored four of her perfect tens on the uneven bars, two on the balance beam and one in the floor exercise. Even with Nadia's perfect scores, the Romanians lost the gold medal to the Soviet Union. Nevertheless, Comaneci became an Olympic icon.
Is there an answer to this question: What is the grading structure?

Answer: a point system from 1 to 15
