Problem: Text: The Five Heartbeats is a 1991 musical drama film directed by Robert Townsend, who co-wrote the script with Keenen Ivory Wayans. Distributed by 20th Century Fox, the film's main cast includes Townsend, Michael Wright, Leon Robinson, Harry J. Lennix, Tico Wells, Harold Nicholas of the Nicholas Brothers, and Diahann Carroll. The plot of the film (which is loosely based on the lives of several artists: The Dells, The Temptations, Four Tops, Wilson Pickett, James Brown, Frankie Lymon, Sam Cooke and others) follows the three decade career of the rhythm and blues vocal group The Five Heartbeats. The film depicts the rise and fall of a Motown inspired soul act through the eyes of one of the Heartbeats, Donald ''Duck'' Matthews.

Question: was the five heartbeats based on a real group?
A: no

Problem: Text: Modern dishes intended for home television use are generally 43 cm (18 in) to 80 cm (31 in) in diameter, and are fixed in one position, for Ku-band reception from one orbital position. Prior to the existence of direct broadcast satellite services, home users would generally have a motorised C-band dish of up to 3 m in diameter for reception of channels from different satellites. Overly small dishes can still cause problems, however, including rain fade and interference from adjacent satellites.

Question: does the size of a satellite dish matter?
A: yes

Problem: Text: Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by the Earth's magnetic field lines. This angle varies at different points on the Earth's surface. Positive values of inclination indicate that the magnetic field of the Earth is pointing downward, into the Earth, at the point of measurement, and negative values indicate that it is pointing upward. The dip angle is in principle the angle made by the needle of a vertically held compass, though in practice ordinary compass needles may be weighted against dip or may be unable to move freely in the correct plane. The value can be measured more reliably with a special instrument typically known as a dip circle.

Question: will the dip be the same everywhere in the world?
A:
no
