उत्तर : 1. "Thermosphere"
व्याख्या :

Answer: A) Thermosphere Explanation: In terms of the Earth's atmosphere, they occupy regions called the thermosphere and the exosphere. The layer through which a satellite orbits depends on the satellite's function and the kind of orbit it has.   The thermosphere is a region of very high temperature that extends from the top of the mesosphere at around 85 kilometers (53 miles) up to 640 kilometers (400 miles) above the Earth's surface. It is called the thermosphere because temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit).   However, despite the high temperatures, the pressure is very low, so satellites don't suffer heat damage.

प्र: What is an example of an inflation risk? 1707 0

उत्तर :
व्याख्या :

Inflation risk, also called purchasing power risk, is the chance that the cash flows from an investment won't be worth as much in the future because of changes in purchasing power due to inflation.   HOW IT WORKS (EXAMPLE): For example, $1,000,000 in bonds with a 10% coupon might generate enough interest payments for a retiree to live on, but with an annual 3% inflation rate, every $1,000 produced by the portfolio will only be worth $970 next year and about $940 the year after that. The rising inflation means that the interest payments have less and less purchasing power. And the principal, when it is repaid after several years, will buy substantially less than it did when the investor first purchased the bonds.

उत्तर : 3. "It prevented railroads from charging farmers more than other customers."
व्याख्या :

Answer: C) It prevented railroads from charging farmers more than other customers. Explanation: In 1887 Congress passed the Interstate Commerce Act, making the railroads the first industry subject to Federal regulation. Congress passed the law largely in response to public demand that railroad operations be regulated.   Railroads discriminated in the prices they charged to passengers and shippers in different localities by providing rebates to large shippers or buyers. These practices were especially harmful to American farmers, who lacked the shipment volume necessary to obtain more favorable rates.
