QUES: Houston was incorporated in 1837 under the ward system of representation. The ward designation is the progenitor of the eleven current-day geographically oriented Houston City Council districts. Locations in Houston are generally classified as either being inside or outside the Interstate 610 Loop. The inside encompasses the central business district and many residential neighborhoods that predate World War II. More recently, high-density residential areas have been developed within the loop. The city's outlying areas, suburbs and enclaves are located outside of the loop. Beltway 8 encircles the city another 5 miles (8.0 km) farther out.
Beside older pre-World War II residences, what is found inside the Loop? 

ANS: central business district

QUES: In the context of chemistry, energy is an attribute of a substance as a consequence of its atomic, molecular or aggregate structure. Since a chemical transformation is accompanied by a change in one or more of these kinds of structure, it is invariably accompanied by an increase or decrease of energy of the substances involved. Some energy is transferred between the surroundings and the reactants of the reaction in the form of heat or light; thus the products of a reaction may have more or less energy than the reactants. A reaction is said to be exergonic if the final state is lower on the energy scale than the initial state; in the case of endergonic reactions the situation is the reverse. Chemical reactions are invariably not possible unless the reactants surmount an energy barrier known as the activation energy. The speed of a chemical reaction (at given temperature T) is related to the activation energy E, by the Boltzmann's population factor e−E/kT – that is the probability of molecule to have energy greater than or equal to E at the given temperature T. This exponential dependence of a reaction rate on temperature is known as the Arrhenius equation.The activation energy necessary for a chemical reaction can be in the form of thermal energy.
What is the probability of molecule to have energy greater than or equal to E at the given temperature T?

ANS: e−E/kT

QUES: Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).
What is one type of competition department stores never face? 

ANS: unanswerable

QUES: Ye Zhiping, the principal of Sangzao Middle School in Sangzao, one of the largest in An County, has been credited with proactive action that spared the lives of all 2,323 pupils in attendance when the earthquake happened. During a three-year period that ended in 2007, he oversaw a major overhaul of his school. During that time he obtained more than 400,000 yuan (US$60,000) from the county education department, money used to widen and strengthen concrete pillars and the balcony railing of all four storeys of his school, as well as secure its concrete floors.
What school principal strengthened his school?

ANS:
Ye Zhiping
