Business and government leaders also consider the inflation rate to be an important general indicator. Inflation is a period of increased spending that causes rapid rises in prices. (51) your money buys fewer goods so that you get (52) for the same amount of money as before, inflation is the problem. There is a general rise (53) the price of goods and services. Your money buys less. Sometimes people describe inflation as a time when "a dollar is not worth a dollar anymore".
Inflation is a problem for all consumers. People who live on a fixed income are hurt the (54) . Retired people, for instance, cannot count on an increase in income as prices rise. Elderly people who do not work face serious problems in stretching their incomes to (55) their needs in time of inflation. Retirement income (56) any fixed income usually does not rise as fast as prices. Many retired people must cut their spending to (57) rising prices. In many cases they must stop (58) some necessary items, such as food and clothing. Even (59) working people whose incomes are going up, inflation can be a problem. The (60) of living goes up, too. People who work must have even more money to keep up their standard of living. Just buying the things they need costs more. When incomes do not keep (61) with rising prices, the standard of living goes down. People may be earning the same amount of money, but they are not living as well because they are not able to buy as many goods and services.
Government units gather information about prices in our economy and publish it as price indexes (62) the rate of change can be determined. A price index measures changes in prices using the price for a (63) year as the base. The base price is set at 100, and the other prices are reported as a (64) of the base price. A price index makes (65) possible to compare current prices of typical consumer goods, for example, with prices of the same goods in previous years.

The TCP protocolis a （1）layer protocol. Each connection connects two TCPs that may be just one physical network apart or located on opposite sides of the globe. In other words, each connection creates a （2） witha length that may be totally different from another path created by another connection. This means that TCP cannot use the same retransmission time for all connections. Selecting a fixed retransnussion time for all connections can result in serious consequences. If the retransmission time does not allow enough time for a （3） to reach the destination and an acknowledgment to reach the source, it can result in retransmission of segments that are still on the way. Conversely, if the retransmission time is longer than necessary for a short path, it may result in delay for the application programs. Even for one single connection, the retransmission time should not be fixed. A connection may be able to send segments and receive （4） faster during nontraffic period than during congested periods. TCP uses the dynamic retransmission time, a transmission time is different for each connection and which may be changed during the same connection. Retransmission time can be made（5） by basing it on the round-trip time (RTT). Several formulas are used for this purpose.
