Problem: Hellenistic period:

Widespread Roman interference in the Greek world was probably inevitable given the general manner of the ascendency of the Roman Republic. This Roman-Greek interaction began as a consequence of the Greek city-states located along the coast of southern Italy. Rome had come to dominate the Italian peninsula, and desired the submission of the Greek cities to its rule. Although they initially resisted, allying themselves with Pyrrhus of Epirus, and defeating the Romans at several battles, the Greek cities were unable to maintain this position and were absorbed by the Roman republic. Shortly afterwards, Rome became involved in Sicily, fighting against the Carthaginians in the First Punic War. The end result was the complete conquest of Sicily, including its previously powerful Greek cities, by the Romans.

Greek cities were absorbed by what republic?

A: Roman


Problem: Despite Laemmle's role as an innovator, he was an extremely cautious studio chief. Unlike rivals Adolph Zukor, William Fox, and Marcus Loew, Laemmle chose not to develop a theater chain. He also financed all of his own films, refusing to take on debt. This policy nearly bankrupted the studio when actor-director Erich von Stroheim insisted on excessively lavish production values for his films Blind Husbands (1919) and Foolish Wives (1922), but Universal shrewdly gained a return on some of the expenditure by launching a sensational ad campaign that attracted moviegoers. Character actor Lon Chaney became a drawing card for Universal in the 1920s, appearing steadily in dramas. His two biggest hits for Universal were The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925). During this period Laemmle entrusted most of the production policy decisions to Irving Thalberg. Thalberg had been Laemmle's personal secretary, and Laemmle was impressed by his cogent observations of how efficiently the studio could be operated. Promoted to studio chief, Thalberg was giving Universal's product a touch of class, but MGM's head of production Louis B. Mayer lured Thalberg away from Universal with a promise of better pay. Without his guidance Universal became a second-tier studio, and would remain so for several decades.
Who was at one time Laemmle's personal secretary?

Answer: Irving Thalberg


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although dance-oriented, electronic pop and ballad-oriented rock dominated the 1980s, soft rock songs still enjoyed a mild success thanks to artists like Sheena Easton, Amy Grant, Lionel Richie, Christopher Cross, Dan Hill, Leo Sayer, Billy Ocean, Julio Iglesias, Bertie Higgins and Tommy Page. No song spent more than six weeks at #1 on this chart during the 1980s, with nine songs accomplishing that feat. Two of these were by Lionel Richie, "You Are" in 1983 and "Hello" in 1984, which also reached #1 on the Hot 100.

Context and question: The length of the pitch for international adult matches is in the range of 100–110 m (110–120 yd) and the width is in the range of 64–75 m (70–80 yd). Fields for non-international matches may be 90–120 m (100–130 yd) length and 45–90 m (50–100 yd) in width, provided that the pitch does not become square. In 2008, the IFAB initially approved a fixed size of 105 m (344 ft) long and 68 m (223 ft) wide as a standard pitch dimension for international matches; however, this decision was later put on hold and was never actually implemented.
What is the length of the pitch for international child matches?
Answer: unanswerable


Question: Yale's Office of Sustainability develops and implements sustainability practices at Yale. Yale is committed to reduce its greenhouse gas emissions 10% below 1990 levels by the year 2020.

Eleven campus buildings are candidates for LEED design and certification. Yale Sustainable Food Project initiated the introduction of local, organic vegetables, fruits, and beef to all residential college dining halls. Yale was listed as a Campus Sustainability Leader on the Sustainable Endowments Institute’s College Sustainability Report Card 2008, and received a "B+" grade overall.

Problem: Sahara:

The central part of the Sahara is hyperarid, with little to no vegetation. The northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs in wadis where moisture collects. In the central, hyperarid part, there are many subdivisions of the great desert such as the Tanezrouft, the Ténéré, the Libyan Desert, the Eastern Desert, the Nubian Desert and others. These absolute desert regions are characterized by their extreme aridity, and some years can pass without any rainfall.

What does the Sahara have little to none of?
