Due to extreme variation in elevation, great variation occurs in the climatic conditions of Himachal . The climate varies from hot and subhumid tropical in the southern tracts to, with more elevation, cold, alpine, and glacial in the northern and eastern mountain ranges. The state has areas like Dharamsala that receive very heavy rainfall, as well as those like Lahaul and Spiti that are cold and almost rainless. Broadly, Himachal experiences three seasons: summer, winter, and rainy season. Summer lasts from mid-April till the end of June and most parts become very hot (except in the alpine zone which experiences a mild summer) with the average temperature ranging from 28 to 32 °C (82 to 90 °F). Winter lasts from late November till mid March. Snowfall is common in alpine tracts (generally above 2,200 metres (7,218 ft) i.e. in the higher and trans-Himalayan region).
Why is there variation in the climate conditions of Lahaul?
A: unanswerable

In 1978, Josep Lluís Núñez became the first elected president of FC Barcelona, and, since then, the members of Barcelona have elected the club president. The process of electing a president of FC Barcelona was closely tied to Spain's transition to democracy in 1974 and the end of Franco's dictatorship. The new president's main objective was to develop Barcelona into a world-class club by giving it stability both on and off the pitch. His presidency was to last for 22 years, and it deeply affected the image of Barcelona, as Núñez held to a strict policy regarding wages and discipline, letting go of such players as Maradona, Romário and Ronaldo rather than meeting their demands.
What was Nunez known to be strict about?
A: wages and discipline

The moratorium ended on January 17, 1977 with the shooting of Gary Gilmore by firing squad in Utah. The first use of the electric chair after the moratorium was the electrocution of John Spenkelink in Florida on May 25, 1979. The first use of the gas chamber after the moratorium was the gassing of Jesse Bishop in Nevada on October 22, 1979. The first use of the gallows after the moratorium was the hanging of Westley Allan Dodd in Washington on January 5, 1993. The first use of lethal injection was on December 7, 1982, when Charles Brooks, Jr., was executed in Texas.
 In what state was Gary Gilmore freed?
A: unanswerable

Although an alloy is technically an impure metal, when referring to alloys, the term "impurities" usually denotes those elements which are not desired. These impurities are often found in the base metals or the solutes, but they may also be introduced during the alloying process. For instance, sulfur is a common impurity in steel. Sulfur combines readily with iron to form iron sulfide, which is very brittle, creating weak spots in the steel. Lithium, sodium and calcium are common impurities in aluminium alloys, which can have adverse effects on the structural integrity of castings. Conversely, otherwise pure-metals that simply contain unwanted impurities are often called "impure metals" and are not usually referred to as alloys. Oxygen, present in the air, readily combines with most metals to form metal oxides; especially at higher temperatures encountered during alloying. Great care is often taken during the alloying process to remove excess impurities, using fluxes, chemical additives, or other methods of extractive metallurgy.
Using fluxes and chemical additives during the alloying process does what?
A:
remove excess impurities
