Problem: Transistor:

The junction forward voltage is the voltage applied to the emitter–base junction of a BJT in order to make the base conduct a specified current. The current increases exponentially as the junction forward voltage is increased. The values given in the table are typical for a current of 1 mA (the same values apply to semiconductor diodes). The lower the junction forward voltage the better, as this means that less power is required to "drive" the transistor. The junction forward voltage for a given current decreases with increase in temperature. For a typical silicon junction the change is −2.1 mV/°C. In some circuits special compensating elements (sensistors) must be used to compensate for such changes.

What is the ideal junction forward voltage?
---
A: lower


Problem: High-definition television:

Colour broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625 line broadcasts.

 The PAL and SECAM were black and white systems where?
---
A: unanswerable


Problem: Carnival:

Carnival is known as Crop Over and is Barbados's biggest festival. Its early beginnings were on the sugar cane plantations during the colonial period. Crop over began in 1688, and featured singing, dancing and accompaniment by shak-shak, banjo, triangle, fiddle, guitar, bottles filled with water and bones. Other traditions included climbing a greased pole, feasting and drinking competitions. Originally signaling the end of the yearly cane harvest, it evolved into a national festival. In the late 20th century, Crop Over began to closely mirror the Trinidad Carnival. Beginning in June, Crop Over runs until the first Monday in August when it culminates in the finale, The Grand Kadooment.

What year did Crop Over begin?
---
A: 1688


Problem: Race (human categorization):

Since the end of the Second World War, France has become an ethnically diverse country. Today, approximately five percent of the French population is non-European and non-white. This does not approach the number of non-white citizens in the United States (roughly 28–37%, depending on how Latinos are classified; see Demographics of the United States). Nevertheless, it amounts to at least three million people, and has forced the issues of ethnic diversity onto the French policy agenda. France has developed an approach to dealing with ethnic problems that stands in contrast to that of many advanced, industrialized countries. Unlike the United States, Britain, or even the Netherlands, France maintains a "color-blind" model of public policy. This means that it targets virtually no policies directly at racial or ethnic groups. Instead, it uses geographic or class criteria to address issues of social inequalities. It has, however, developed an extensive anti-racist policy repertoire since the early 1970s. Until recently, French policies focused primarily on issues of hate speech—going much further than their American counterparts—and relatively less on issues of discrimination in jobs, housing, and in provision of goods and services.

What type of model of public policy does France maintain?
---
A:
color-blind
