A supernova is a brief [#permalink] New post 16 Dec 2015, 05:32
A supernova is a brief stellar explosion so luminous that it can briefly outshine an entire galaxy. While
the explosion itself takes less than fifteen seconds, supernovae take weeks or months to fade from view;
during that time, a supernova can emit an amount of energy equivalent to the amount of energy the sun is
expected to radiate over its entire lifespan.
5 Supernovae generate enough heat to create heavy elements, such as mercury, gold, and silver. Although
supernovae explode frequently, few of them are visible (from Earth) to the naked eye.
In 1604 in Padua, Italy, a supernova became visible, appearing as a star so bright that it was visible in
daylight for more than a year. Galileo, who lectured at the university, gave several lectures widely attended by
the public. The lectures not only sought to explain the origin of
10
the “star” (some posited that perhaps it was merely “vapour near the earth”), but seriously undermined the
views of many philosophers that the heavens were unchangeable. This idea was foundational to a worldview
underpinned by a central and all-important Earth, with celestial bodies merely rotating around it.

Which of the following can be inferred by the passage?
1,Supernovae can take over a year to fade from view.
2,Prior to 1604, no one had ever seen a supernova.
3,Galileo convinced philosophers of the incorrectness of their views.

Here my choice is 2 because supernova became visible in 1604.
but i have no strong reason to choose 1.
Please need explanation.

2,Prior to 1604, no one had ever seen a supernova.

It CANNOT be inferred from the passage.
- The first paragraph consists of five sentences telling us about supernova and the characteristics of its explosion.
- Next, it states clearly about even though supernova explodes frequently (with massive energy), few of them are visible to naked eye.
- At this very idea, it uses an example that in 1604 in Padua, Italy, a supernova exploded and became visible. When using this example, it may contradict the common notion that most supernovae are most invisible to the eye AND the passage is diverting to another idea about Galileo's lectures and other outcomes.

Analysing:
- Logically, when saying "In 1604 in Padua, Italy, a supernova became visible...", it is obviously UNNECESSARY meant that before 1604, NO ONE had ever seen a supernova.
- Things are more clear when you tailor the example to the flow of the passage. By this action, you understand that the example "aims" for other ideas and from the example only we cannot INFER "2" from it.

Thing to remember:
- Pay attention to the extreme words such as "no one", "nothing", "all". It is worthy of consideration when the sentence uses these terms because there is higher chance of overgeneralization and extreme.

I hope this helps.

The primary purpose of the passage is to
(A) give the history of supernovae
(B) describe a shift in thought as a result of a natural event
(C) juxtapose two opposing views about supernovae
(D) corroborate the view that the earth is not central to the universe
(E) explain how science and philosophy interrelate

B


Consider each of the answer choices separately and indicate all that apply.

Which of the following can be inferred by the passage?
  • Supernovae can take over a year to fade from view.
  • Prior to 1604, no one had ever seen a supernova.
  • Galileo convinced philosophers of the incorrectness of their views.

The author mentions which of the following as a result of the supernova of 1604?

(A) The supernova created and dispersed the heavy elements out of which the Earth and everything on it is made.
(B) Galileo explained the origin of the supernova.
(C) The public was interested in hearing lectures about the phenomenon.
(D) Galileo’s lectures were opposed by philosophers.
(E) Those who thought the supernova was “vapour” were proved wrong.

Your answers are correct and the passage was a bit convoluted. On the hard side.

However, please provide your explanations.

Thank you a lot

The passage has this information :

Galileo, who lectured at the university, gave several lectures widely attended by the public

Unless public is interested they would not attend. Hence C

For the second question, why isn't it 'C"?
Since Galileo did state his point about supernova, thus proving the philosophers wrong (although, I do agree, the passage doesn't say anything about the philosophers' response, but still)

The answer choice is not about proving philosophers wrong, but convincing philosophers that they are wrong. Nowhere in the passage it says that Galileo tried to convince philosophers
