Five and a half years into his presidency, George Bush finally vetoed a bill this week. Oddly enough, it was one that most Americans support: it would have expanded foderal funding for embryonic stem-cell research. The House and Senate had both passed the bill by wide, but not veto-proof margins, so Mr. Bush’s word is final, at least until after the mid-term elections in November.
Stem cells are cells that have not yet decided what they want to be when they grow up. That is, they can become blood cells, brain cells, or pretty much any other type of cell. Their versatility makes them extremely useful for medical research. The ethical snag is that the best stem cells are harvested from human embryos, killing them. For the most ardent pro-lifers, including Mr. Bush and many of his core supporters, that is murder. Proponents of embryonic stem-cell research point out that hordes of embryos are created during fertility treatment, and the vast majority of these are either frozen indefinitely or destroyed. Is it really wrong to use them for potentially life-saving research Yes, said Mr. Bush on July 19th, flanked by some families who had "adopted" other people’s frozen embryos and used them to have children of their own.
Mr. Bush’s veto does not kill stem-cell research. Scientists who spurn federal cash may do as they please. The government still pays for research on stem cells taken from adults, a process that does not kill the donor. And a decision by Mr. Bush in 2001 allows federally-funded scientists to experiment on the few dozen embryonic stem-cell "lines" that already existed then, which can be propagated in a laboratory.
Nonetheless, scientists are furious with Mr. Bush. Federal funding would surely push them faster towards those elusive cures. Research based on adult stem cells may be promising, but not nearly as promising as that based on embryonic ones. There are worries that those few dozen embryonic stem-cell lines represent too narrow a gene pool, and that they cannot be endlessly extended without damaging them. Other countries, such as Britain and China, are enthusiastically experimenting on embryonic stem cells. But the world’s most innovative nation is hanging back.
The expression "snag" ( Line 3, Paragraph 2) most probably means ______.

A:trap. B:obstacle. C:criticism. D:advisory.

Questions from 31 to 35 are based on the following passage: A garment label is more than just a piece of fabric. It is something that draws the attention of customers to the garment. In today’s times, labels actually help in selling a garment. Customers decide whether to buy a piece of apparel or not on the basis of its label. Labels communicate to the customer what types of materials have been used in making the garment. Different manufacturers use their own special type of labels to create their own distinct identity. A label might be custom-made by a manufacturer to make it unique. Beautiful, customized labels add to the beauty and style of the garment. Each brand produced by the manufacturer is usually distinguishable on the basis of a special symbol, color or word. This is reflected through the label. Garment labels can be made using several fabrics, in different types of finishes and can be attached to the garment in different styles. The fabrics that are commonly used in the preparation of labels are satin, damask, semi-damask and taffeta. In some cases, cotton, canvas and felt are also used in making labels. Satin is the most used fabric in preparing labels. Leather labels are generally used in case of jeans and pants. PVC labels are used in pants and bags. Satin is soft on the skin and looks very pretty initially. However, it is not one of the best fabrics to be used in labels because it is very thin and can snag easily. Labels made using taffeta are stiffer than those of satin and do not snag as easily. However, taffeta labels can irritate the skin of the customers. Damask and semi-damask are ideal fabrics for making labels. Damask labels are soft even after finishing and do not cause any irritation to the customer. Semi-damask is similar to damask in feel, but it costs lesser than damask. According to the passage, which statement is NOT true（ ）

A:A garment label has been a “spokesman” for the certain brand. B:Nowadays, labels have been one of the most influentially decisive factors in the customer’s purchasing performance. C:A unique label adds to the beauty and attraction of the garment. D:Labels are somewhat more important than the garments.
