标题: 请教两道题，不知如何解。

Q9:

Press Secretary: Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive(报复性的) desire to punish legislative districts controlled by opposition parties. They offer as evidence the fact that 90 percent of the projects canceled were in such districts. But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

Which of the following is an assumption on which the press secretary’s argument depends?

Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.

The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.

The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.

The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.

Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

Q11:

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species to recover.

Which of the following, if true, most seriously undermines the argument?

Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.

It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.

The number of snow geese taken by hunters each year has grown every year for several years.

As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.

In the snow goose’s winter habitats, the goose faces no significant natural predation.

建议按照题号搜索一下以前的讨论，应该就有收获。把题号放到标题中也。

如果没有讨论过，大家看到题号也方便来讨论。太晚了，see you。
