Problem: Universal Studios:

By the early 1940s, the company was concentrating on lower-budget productions that were the company's main staple: westerns, melodramas, serials and sequels to the studio's horror pictures, the latter now solely B pictures. The studio fostered many series: The Dead End Kids and Little Tough Guys action features and serials (193843); the comic adventures of infant Baby Sandy (193841); comedies with Hugh Herbert (193842) and The Ritz Brothers (194043); musicals with Robert Paige, Jane Frazee, The Andrews Sisters, and The Merry Macs (193845); and westerns with Tom Mix (193233), Buck Jones (193336), Bob Baker (193839), Johnny Mack Brown (193843); Rod Cameron (194445), and Kirby Grant (194647).

When did westerns with Johnny Rod Brown run?

Problem: Antenna (radio):

Consider a half-wave dipole designed to work with signals 1 m wavelength, meaning the antenna would be approximately 50 cm across. If the element has a length-to-diameter ratio of 1000, it will have an inherent resistance of about 63 ohms. Using the appropriate transmission wire or balun, we match that resistance to ensure minimum signal loss. Feeding that antenna with a current of 1 ampere will require 63 volts of RF, and the antenna will radiate 63 watts (ignoring losses) of radio frequency power. Now consider the case when the antenna is fed a signal with a wavelength of 1.25 m; in this case the reflected current would arrive at the feed out-of-phase with the signal, causing the net current to drop while the voltage remains the same. Electrically this appears to be a very high impedance. The antenna and transmission line no longer have the same impedance, and the signal will be reflected back into the antenna, reducing output. This could be addressed by changing the matching system between the antenna and transmission line, but that solution only works well at the new design frequency.

What effect occurs when the signal is reflected back into the antenna?
---
A: reducing output

Problem: Lancashire:

The Duchy of Lancaster is one of two royal duchies in England. It has landholdings throughout the region and elsewhere, operating as a property company, but also exercising the right of the Crown in the County Palatine of Lancaster. While the administrative boundaries changed in the 1970s, the county palatine boundaries remain the same as the historic boundaries. As a result, the High Sheriffs for Lancashire, Greater Manchester and Merseyside are appointed "within the Duchy and County Palatine of Lancaster".

When was the Duchy of Lancaster established?

A: unanswerable

Problem: Bacteria:

Bacteria exhibit an extremely wide variety of metabolic types. The distribution of metabolic traits within a group of bacteria has traditionally been used to define their taxonomy, but these traits often do not correspond with modern genetic classifications. Bacterial metabolism is classified into nutritional groups on the basis of three major criteria: the kind of energy used for growth, the source of carbon, and the electron donors used for growth. An additional criterion of respiratory microorganisms are the electron acceptors used for aerobic or anaerobic respiration.

How is bacterial metabolism determined?

nutritional groups
