question:
Article: In 1809, Mary Kies received the first U.S. patent issued to a woman. Kies , a Connecticut native , invented a process for weaving straw with silk or thread. First Lady Dolley Madison praised her for improving the nation's het industry. Unfortunately , the patent file was destroyed in a big fire in 1836. Until about 1840, only 20 U.S. patents were issued to women. The inventions were related to clothes, tools ,cook stoves and fireplaces. Patent is the "ownership" of an invention and only the inventor(s) can apply for it. In the past , women were not allowed to have equal rights of property ownership and many women patented their inventions under their husbands' or fathers' name. Women were also prevented from receiving higher education necessary for inventing. Here are a few examples to be noticed, and from these examples, we know enough reasons for encouraging girls and women to pursue technology-based courses and careers. The women inventors took annually granted U.S. patents rising fro;m 2.6 percent in 1977 to 10.3 percent in 1998. The majority of the U.S. woman-inventor patents are in the chemical technologies. In 1996, every eleven U.S. patent grant included one woman inventor. In the past 20 years, about 83 percent of the U. S. patent grants to women were for utility patents , 16.5 percent for design patents, and 0.5 percent for plant patents. About 35 percent of the U.S woman-inventor patents granted during the 1977 to 1996 period originated form California , New York or New Jersey. Today, hundreds of thousands of women apply for and receive patents every year. About 20% of all inventors are currently female and that number will quickly rise to 50% over the next generation.
Answer: praised by Mary Kies
answer:
According to the passage, Dolley Madison was _ .

question:
Article: Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employers and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services wanted by the community. Although the size of the workforce depends a great deal on the size of the total population, there are several other influences which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were a balanced spread age distribution. If the population naturally grows rapidly, the number of births greatly exceeds the number of deaths then as a total population increases proportion of the workforce declines. Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it. In that situation the population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate. The age distribution of the population has several important effects on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes, finance must be available for that purpose. If the size of the workforce is small to the total population, then the government tax revenue is ly low and either the government has less money available to it or workforce members have to be taxed more heavily.
Answer: people who are available to work and earn income
answer:
In the passage "labor force" is defined as _ .

question:
Article: Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air. One of these is a condition called hypoxia . It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules cross the tissues in the lungs and reach the bloodstream. The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body. One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to _ by beating harder and faster. This can make the traveler feel tired. These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack. Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body's ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying.
Answer: advise people not to smoke or drink alcohol
answer:
The author writes the passage mainly to _ .
