For all young Australians who are neither certifie...
For all young Australians who are neither certified as insane nor serving prison sentences of a year or more, a solemn public duty follows hot on the heels of the excitement of their twenty-first birthday. They must register as voters. Having done so, they cannot, as can some American or English adults if they so wish, then forget all about it—voting is compulsory in Australia. Failure to vote without a "true, valid, and sufficient reason" can result in a fine for an Australian citizen. Australians must vote frequently, too, for in proportion to its size, Australia is a much-governed country. For its ten million persons it has seven parliaments—one for each of six states and one commonwealth, or federal, parliament with representatives from all states. Every adult, unless he lives in one of the two territories that do not have state status, must do his share in electing both state and federal representatives. Whats more, with only one exception, these parliaments have two houses each and comprise among them 701 members. This may seem a great many politicians to govern Australias relatively small population of ten million especially when one considers that 630 members of Britains House of Commons govern forty million people. But just as government in the United States and England developed gradually as the result of events in those two countries, so the Australian system has developed in response to the needs of the nation.
What follows an Australians twenty-first birthday？
A．Termination of any prison sentence.
B．Public solemnity.
C．Voting in a national election.
D．Registration to vote.

In computing, passwords are commonly used to limit access to official users. Yet the widespread use of passwords has serious drawbacks. Office workers now have to remember an average of twelve system passwords. In theory they should use different passwords for each site, but in reality these would be impossible to remember, so many people use the same password for all.
An additional problem is that the majority use simple words such as "hello", or names of family members, instead of more secure combinations of numbers and letters, such as 6ANV76Y. This permits computer hackers to download dictionaries and quickly find the word that allows them access.
When system users forget their passwords there is extra expense in supplying new ones, while if people are forced to change passwords frequently they often write them down, making systems even less secure. Therefore, it is clear that the idea of passwords, which have been used as security devices for thousands of years, may need rethinking.
One possible alternative has been developed by the American firm Real User, and is called "passfaces". In order to access the system a worker has to select a series of photographs of faces from a randomly (随机地) generated sequence. If the pictures are selected in the correct order, access is granted. This concept depends on the human ability to recognize and remember a huge number of different faces, and the advantage is that such a sequence cannot be told to anyone or written down, so is more secure. It is claimed that the picture sequence, which used photographs of university students, is easier to remember than passwords, and it has now been adopted for the United States Senate.
What is the disadvantage of passwords as mentioned in Paragraph 1？
A．They do not ensure security.
B．They are difficult to remember.
C．They have to be changed frequently.
D．They limit computer accessibility.

In any country the wages commanded by laborers who have comparable skills but who work in various industries are determined by the productivity of the least productive unit of labor, i.e., that unit of labor which works in the industry which has the greatest economic disadvantage. We will represent the various opportunities of employment in a country like the United States by symbols: A, standing for a group of industries in which we have exceptional, economic advantages over foreign countries; B, for a group in which our advantages are less; C, one in which they are still less; D, the group of industries in which they are least of all.
When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population.
But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell.
After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions.
When C and D are established, workers in these industries______.
A．receive higher wages than do the workers in A and B
B．receive lower wages than do the workers in A and B
C．are not affected so adversely by the levying of duties as are workers in A and B
D．receive wages equal to those workers in A and B
