[单项选择]山奇是一种有降血脂特效的野花。它数量特别稀少，正濒临灭绝。但是，山奇可以通过和雏菊的花粉自然杂交产生山奇一雏菊杂交种子。因此，在山奇尚存的地域内应当大量地人工培育雏菊，虽然这种杂交品种会失去父本或母本的一些重要特性，如不再具有降血脂的特效，但这是避免山奇灭绝的几乎唯一的方式。
上述论证依赖于以下哪项假设

Ⅱ．在山奇尚存的地域内没有野生雏菊。
Ⅲ．山奇一雏菊杂交种子具有繁衍后代的能力。

C. 只有Ⅲ。
D. 只有Ⅱ和Ⅲ。
E. Ⅰ、Ⅱ和Ⅲ。

[不定项选择题]资料：Google and Uber have grabbed most of the attention regarding the advent of self-driving cars, but on Sunday, Lyft threw down the ultimate challenge: A majority of autonomous vehicles for Lyft within a mere five years.
The bold claim was made by Lyft co-founder John Zimmer in a post on Medium outlining his company's vision for the next decade.
"Within five years a fully autonomous fleet of cars will provide the majority of Lyft rides across the country," said Zimmer, indicating that early versions of such cars have been in operation in San Francisco and Phoenix.
Usually when tech founders lay out their vision, it’s typical to hear grand claims that almost push the boundaries of believability. That's what tech innovation is about. But in the case of self-driving cars, the situation is a bit more complicated.
Uber has already begun rolling out self-driving car tests in Pittsburgh and Google is hard at work on the same kind of solution on the West Coast. Therefore, talk of getting self-driving cars on the road is, at this point, less about the technology and more about logistics. We know Google has enough cash to triple down on any initiative it decides to tackle. And as the current ride-sharing leader in the U.S., Uber has enough market share-powered credibility that a future including self-driving Uber cars isn't unrealistic.
Today there are some internet-based ride sharing system but to overcome the critical mass the system has to be real-time, automated and extremely easy to use.
However in the case of Lyft, which continues to struggle against Uber (one report claims that Uber has over 80 percent market share in the U.S.), such a short timeline toward rolling out a fleet of self-driving cars seems somewhat ambitious. Nevertheless, Zimmer continues his vision essay with even more bold predictions.
"By 2025, private car ownership will all but end in major U.S. cities," says Zimmer, a prediction that, if it turns out to be true, would mean it would take just eight years for the majority of the human-driven cars on U.S. roads to disappear. Possible? Sure. Likely? Eight years seems like, once again, a bit of wishful thinking on Zimmer's part.
Remember, it hasn't even been 10 years since the arrival of the iPhone, and as recent events prove, smartphones are still a category that can yield catastrophic results if not done right. And those are just mobile devices, not vehicles entrusted with transporting and protecting human lives.
To be fair, Zimmer's essay does offer some facts and figures in an attempt to back up his positions, but much of it doesn't appear to take into account variables such as the heavily embedded interests of automobile companies still relying on consumer auto sales, as well as the many legal and roadway logistics that will need to be addressed in order to bring about this massive transformation in such a short time.
Oddly, Zimmer's vision does little to address the millions of human jobs that will be lost once self-driving cars displace not only taxi drivers, but truck drivers.
"We believe that in the first five or more years following the introduction of autonomous vehicles, the need for human drivers will actually increase, not decrease," writes Zimmer. "When autonomous cars can only solve a portion of those trips, more Lyft drivers will be needed to provide service to the growing market of former car owners," writes Zimmer.
But what about after five years, when autonomous cars can provide full service? What about the human drivers? The pushback from human drivers losing work will likely be another, major ripple in the evolution of self-driving cars, as well as other automated systems entering U.S. society in coming years.
However, none of these logistical issues diminish Zimmer's ideas. His vision of the future of autonomous vehicles seems quite logical and in step with most who work in and watch the space closely. But the speed bump in accepting his vision wholesale is his ambitious self-driving car timeline in general, and for Lyft in particular.
A.We need to reach everyone’s potential to realize self-driving cars
B.There are still many problems to be solved in self-driving cars
C.Lyft co-founder says most of its cars will be autonomous in 5 years
D.The advantages and disadvantages of self-driving cars
