QUES: After the death of the president Benito Juarez in 1872, the first magistracy of the country was occupied by the vice-president Sebastian Lerdo de Tejada, who called for new elections. Two candidates were registered; Lerdo de Tejada and General Porfirio Diaz, one of the heroes of the Battle of Puebla which had taken place on May 5, 1862. Lerdeo de Tejada won the election, but lost popularity after he announced his intent to run for re-election. On March 21, 1876, Don Porfirio Diaz rebelled against President Sebastian Lerdo de Tejada. The Plan of Tuxtepec defended the "No Re-election" principle. On June 2, 1876 the garrisons in the state of Chihuahua surrendered to the authority of General Porfirio Diaz; Governor Antonio Ochoa was arrested until all the Lerdista forces were suppressed throughout the state. Porfirio Diaz then helped Tiras regain the governorship of the state of Chihuahua allowing for the Plan of Tuxtepec to be implemented. The victory of the Plan of Tuxtepec, gave the interim presidency to Jose Maria Iglesias and later, as the only candidate, the General Porfirio Diaz assumed the presidency on May 5, 1877. During the first years of the Porfiriato (Porfirio Diaz Era), the Diaz administration had to combat several attacks from the Lerdista forces and the Apache. A new rebellion led by the Lerdista party was orchestrated from exile in the United States. The Lerdista forces were able to temporarily occupy the city of El Paso del Norte until mid-1877. During 1877 the northern parts of the state suffered through a spell of extreme drought which were responsible for many deaths in El Paso del Norte.
In which year did Benito Juarez die?

ANS: 1872

QUES: An early advantage of AC is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic "universal" AC/DC motor to be largely replaced with the three-phase induction motor fed by a variable frequency drive, a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation.
No modern electric locomotives are designed to handle what?

ANS: unanswerable

QUES: The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place.
Where did beavers keep animals from grazing?

ANS: unanswerable

QUES: Located in the American South, Houston is a diverse city with a large and growing international community. The metropolitan area is home to an estimated 1.1 million (21.4 percent) residents who were born outside the United States, with nearly two-thirds of the area's foreign-born population from south of the United StatesMexico border. Additionally, more than one in five foreign-born residents are from Asia. The city is home to the nation's third-largest concentration of consular offices, representing 86 countries.
How many foreign born Houstonites are from Asia?

ANS:
one in five
