The human body can tolerate only a small range of temperature, especially when the person is engaged in vigorous activity. Heat {#blank#}1{#/blank#} usually occur when large amounts of water and/or salt are lost through oversweating following exhausting exercise. When the body becomes overheated and cannot {#blank#}2{#/blank#} this overheatedness, heat exhaustion and heat stroke are possible.

    Heat exhaustion is generally {#blank#}3{#/blank#} by sweaty skin, tiredness, sickness, dizziness, plentiful sweating, and sometimes fainting, resulting from a(n) {#blank#}4{#/blank#} intake of water and the loss of fluids.  First aid treatment for this condition includes having the victim lie down, {#blank#}5{#/blank#} the feet 8 to 12 inches, applying cool, wet cloths to the skin, and giving the victim sips of salt water (1 teaspoon per glass, half a glass every 15 minutes) over a 1-hour period.

    Heat stroke is much more serious; it is a(n) {#blank#}6{#/blank#} life-threatening situation. The characteristics of heat stroke are a high body temperature (which may reach 106° F or more); a rapid pulse; hot, dry skin; and a blocked sweating {#blank#}7{#/blank#}. Victims of this condition may be unconscious, and first-aid measures should be {#blank#}8{#/blank#} at quickly cooling the body. The victim should be placed in a tub of cold water or {#blank#}9{#/blank#} sponged with cool water until his or her temperature is sufficiently lowered. Fans or air conditioners will also help with the cooling {#blank#}10{#/blank#}. Care should be taken, however, not to over-chill the victim once the temperature is below 102° F.

    An {#blank#}1{#/blank#} arson attack on a respected Japanese animation studio left a shocked nation grieving, as investigators looked to identify victims and determine a possible motive in one of the deadliest acts of {#blank#}2{#/blank#} in Japan's modern history.

    A total of 33 people — many of them young — were killed a day earlier when a man {#blank#}3{#/blank#} to douse flammable liquid through the Kyoto Animation Co. studio and set it alight, {#blank#}4{#/blank#} an inferno, officials said. Some 36 others were injured, about 10 critically.

    The blaze at the production house struck at a pillar of Japan's anime industry, an obsession in the country and a cherished cultural {#blank#}5{#/blank#}. Kyoto Animation, known as KyoAni, had produced hits such as "Lucky Star," "K-On!" and "Haruhi Suzumiya, " {#blank#}6{#/blank#} worldwide acclaim for its skilled drawings.

    Outside the charred shell of the company's workspace in Kyoto's outskirts on Friday, crowds of well-wishers left flowers and messages of support for the victims. Many bowed, or {#blank#}7{#/blank#} down and prayed as they offered their respects.

    The {#blank#}8{#/blank#}, Shinji Aoba, aged 41, remained in the hospital after {#blank#}9{#/blank#} burns all over his body. A woman who saw police detain the man a day earlier told reporters that he "seemed to be discontented, he seemed to get angry, shouting something about how he had been plagiarized, " according to Reuters.

    Hideaki Hatta, a co-founder and president of Kyoto Animation, said Thursday that the studio had been receiving {#blank#}10{#/blank#}, including emails threatening murder. He said the attack had "broken our hearts."

It is one of the great unsolved {#blank#}1{#/blank#}of this century.

He was being very {#blank#}2{#/blank#}about where he was going.
