QUES: FETs are divided into two families: junction FET (JFET) and insulated gate FET (IGFET). The IGFET is more commonly known as a metal–oxide–semiconductor FET (MOSFET), reflecting its original construction from layers of metal (the gate), oxide (the insulation), and semiconductor. Unlike IGFETs, the JFET gate forms a p–n diode with the channel which lies between the source and drain. Functionally, this makes the n-channel JFET the solid-state equivalent of the vacuum tube triode which, similarly, forms a diode between its grid and cathode. Also, both devices operate in the depletion mode, they both have a high input impedance, and they both conduct current under the control of an input voltage.
How many groups are FETs split into?

ANS: two

QUES: Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.
What kinds of fabrics can be made from blended fibers?

ANS: knitted or woven

QUES: Another popular event held in February, which is early spring in Tucson, is the Fiesta de los Vaqueros, or rodeo week, founded by winter visitor, Leighton Kramer. While at its heart the Fiesta is a sporting event, it includes what is billed as "the world's largest non-mechanized parade". The Rodeo Parade is a popular event as most schools give two rodeo days off instead of Presidents Day. The exception to this is Presidio High (a non-public charter school), which doesn't get either. Western wear is seen throughout the city as corporate dress codes are cast aside during the Fiesta. The Fiesta de los Vaqueros marks the beginning of the rodeo season in the United States.
Who started the Fiesta de los Vaqueros?

ANS: Leighton Kramer

QUES: In early August 2008, Iowa Labour Commissioner David Neil announced that his department had found that Agriprocessors, a kosher meatpacking company in Postville which had recently been raided by Immigration and Customs Enforcement, had employed 57 minors, some as young as 14, in violation of state law prohibiting anyone under 18 from working in a meatpacking plant. Neil announced that he was turning the case over to the state Attorney General for prosecution, claiming that his department's inquiry had discovered "egregious violations of virtually every aspect of Iowa's child labour laws." Agriprocessors claimed that it was at a loss to understand the allegations. Agriprocessors' CEO went to trial on these charges in state court on 4 May 2010. After a five-week trial he was found not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.
What was the verdict?

not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.
