Problem: Since the introduction of league football, most club sides play a number of friendlies before the start of each season (called pre-season friendlies). Friendly football matches are considered to be non-competitive and are only used to "warm up" players for a new season/competitive match. There is generally nothing competitive at stake and some rules may be changed or experimented with (such as unlimited substitutions, which allow teams to play younger, less experienced, players, and no cards). Although most friendlies are simply one-off matches arranged by the clubs themselves, in which a certain amount is paid by the challenger club to the incumbent club, some teams do compete in short tournaments, such as the Emirates Cup, Teresa Herrera Trophy and the Amsterdam Tournament. Although these events may involve sponsorship deals and the awarding of a trophy and may even be broadcast on television, there is little prestige attached to them.
When do football clubs still play friendlies?
The answer is the following: before the start of each season

Problem: In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks near his Neuchâtel home which he believed originated to the west in the Bernese Oberland. Because of his work he came to be known as the "father of the ice-age concept" although other naturalists before him put forth similar ideas.
Who noted the severe erosion of the mountains?
The answer is the following: Louis Agassiz

Problem: This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C♯ (61) can be labeled 60.5.
A440 in linear pitch are what size?
The answer is the following: 69

Problem: However, the NSA's report was completely disproved by Croatian experts. The report failed to recognize that Tito was a native speaker of the very distinctive local Kajkavian dialect of Zagorje. The acute accent, present only in Croatian dialects, which Tito is perfectly pronouncing, is the strongest proof of Tito's belonging to Kajkavian dialect.
Croatian experts disproved the report from which group concerning Tito's ethnic origins?
The answer is the following:
NSA
