This is not only a seemingly effective way to select a child’s gender. It also brings a host of ethical and practical considerations ----especially for the majority of families who use the technique for nonmedical reasons.

The clinic offers sex selection for two purposes: to help couples avoid passing on a sex-linked genetic disease and to allow those who already have a child to “balance” their family by having a baby of the opposite sex.

Blaucer said the company has had an impressive success rate: 91 percent of the women who become pregnant after sorting for a girl are successful, while 76 percent who sort for a boy and get pregnant are successful.

The technique separates sperm based on the fact that the X chromosome is larger than the Y chromosome. A machine is used to distinguished the size differences and sort the sperm accordingly.

Without question there are plenty of bargains to be had at sales time ----particularly at the top-quality shops whose reputation depends on having only the best and newest goods in stock each season. They tend, for obvious reasons, to be the fashion or seasonal goods which in due course become the biggest bargains.

It is true that some goods are specially brought in for the sales but these too can provide exceptional value. A manufacturer may have the end of a range left in his hands and be glad to sell

the lot off cheaply to shops; or he may have a surplus of a certain material which he is glad to make up and get rid of cheaply; or he may be prepared to produce a special line at low cost merely to keep his employees busy during slack period. He is likely to have a good many “seconds” available and if their defects are trifling these may be particularly good bargains.

Nevertheless, sales do offer a special opportunity for sharp practices and shoppers need to be extra critical. For example the “second” should be clearly marked as such and not sold as if they were perfect. The term “substandard,” incidentally, usually indicates a more serious defect than “seconds.” More serious is the habit of marking the price down from an alleged previous price which is in fact fictitious. Mis-description of this and all other kinds is much practiced by the men who run one-day sales of carpets in church halls and the like. As the sellers leave the district the day after the sale there is little possibility of redress. In advertising sales, shops may say “only 100 left” when in fact they have plenty more; conversely they may say “10,000 at half-price” when only a few are available at such a drastic reduction. If ever the warning “let the buyer beware” were necessary it is during sales.

A Cheapest goods B Newest goods C Seasonal goods D Goods in stock 64. The second paragraph deals with all of the following types of goods EXCEPT ____

A surplus goods B low-cost goods C the end lot goods D exceptionally valued goods 65. In order to maintain his business during a bad time, a manufacturer may ____

A have his goods produced at low cost. B sell his goods at a very low price. C have his employees sell his goods. D try to produce high quality goods. 66. The passage suggests that “seconds”____________

A are of better quality than “substandard goods” B attract buyers as particularly good bargains.

C are defective but marked as perfect. D are goods with serious defects 67. The word “redress” ( the underlined word in the last paragraph) probably means ____ A dressing again B change of address

C compensation for something wrong. D selling the same product at different prices. 68. During sales shoppers should ____
