One reason human beings can thrive in all kinds of climates is that they can control the qualities of the air in the enclosed spaces in which they live. Air conditioning is the use of mechanical systems to【C1】that control in such places【C2】homes, offices, theaters, institutions, factories, airplanes, and automobiles. The most familiar type of air conditioning is summertime cooling. Although important, this is【C3】one of several aspects of air conditioning. Other applications【C4】the control of the humidity (or air moisture), cleanliness, circulation of the air, and heating. Tests have【C5】that people generally feel best【C6】certain temperature, humidity, and air velocity conditions.

The idea that music makes you smarter has received considerable attention from scholars and the media. Current interest in【C1】between music and intelligence stems from two independent areas of research. One focuses on short-term effects of【C2】listening to music. The other is on a seperate【C3】of research, which examines whether music lessons have【C4】benefits that extend to non-musical areas of cognition. Such【C5】could be unique to children who take music lessons for long periods of time【C6】their experiences differ substantially from those of other children. Music lessons【C7】long periods of focused attention, memorization of【C8】 musical passages, learning about a variety of musical structures, and 【C9】mastery of technical skills and the conventions【C10】the expression of emotions in performance. This【C11】of experiences could have a positive impact on cognition, particularly during the childhood years, when brain development is highly【C12】and sensitive to environmental influence. Previous findings are【C13】with the hypothesis that music lessons promote intellectual development.
