Problem: Jews:

According to a report published in 2014, about 43% of all Jews reside in Israel (6.1 million), and 40% in the United States (5.7 million), with most of the remainder living in Europe (1.4 million) and Canada (0.4 million). These numbers include all those who self-identified as Jews in a socio-demographic study or were identified as such by a respondent in the same household. The exact world Jewish population, however, is difficult to measure. In addition to issues with census methodology, disputes among proponents of halakhic, secular, political, and ancestral identification factors regarding who is a Jew may affect the figure considerably depending on the source.

How many non Jewish people live in the United States?

Problem: House music:

The tour in March 1987[citation needed] of Knuckles, Jefferson, Fingers Inc. (Heard) and Adonis as the DJ International Tour boosted house in the UK. Following the number-one success of MARRS' "Pump Up The Volume" in October, the years 1987 to 1989 also saw UK acts such as The Beatmasters, Krush, Coldcut, Yazz, Bomb The Bass, S-Express, and Italy's Black Box opening the doors to a house music onslaught on the UK charts. Early British house music quickly set itself apart from the original Chicago house sound;[citation needed] many of the early hits were based on sample montage, rap was often used for vocals (far more than in the US),[citation needed] and humor was frequently an important element.

What was not used for vocals?

Problem: To Kill a Mockingbird:

Lee has said that To Kill a Mockingbird is not an autobiography, but rather an example of how an author "should write about what he knows and write truthfully". Nevertheless, several people and events from Lee's childhood parallel those of the fictional Scout. Lee's father, Amasa Coleman Lee, was an attorney, similar to Atticus Finch, and in 1919, he defended two black men accused of murder. After they were convicted, hanged and mutilated, he never tried another criminal case. Lee's father was also the editor and publisher of the Monroeville newspaper. Although more of a proponent of racial segregation than Atticus, he gradually became more liberal in his later years. Though Scout's mother died when she was a baby, Lee was 25 when her mother, Frances Cunningham Finch, died. Lee's mother was prone to a nervous condition that rendered her mentally and emotionally absent. Lee had a brother named Edwin, wholike the fictional Jemwas four years older than his sister. As in the novel, a black housekeeper came daily to care for the Lee house and family.

At what age did Harper Lee's mother die?

Problem: Electric motor:

Stepper motors can be rotated to a specific angle in discrete steps with ease, and hence stepper motors are used for read/write head positioning in computer floppy diskette drives. They were used for the same purpose in pre-gigabyte era computer disk drives, where the precision and speed they offered was adequate for the correct positioning of the read/write head of a hard disk drive. As drive density increased, the precision and speed limitations of stepper motors made them obsolete for hard drivesthe precision limitation made them unusable, and the speed limitation made them uncompetitivethus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a typical (cone type) loudspeaker. This structure was used for a while to position the heads. Modern drives have a pivoted coil mount; the coil swings back and forth, something like a blade of a rotating fan. Nevertheless, like a voice coil, modern actuator coil conductors (the magnet wire) move perpendicular to the magnetic lines of force.)

To what device does the term, "voice coil" not historically refer?
