Astronomers theorize that a black hole forms when a massive object shrinks catastrophically under its own gravity, leaving only a gravitational field so strong that nothing escapes it. Astronomers must infer the existence of black holes, which are invisible, from their gravitational influence on the visible bodies surrounding them. For example, observations indicate that gas clouds in galaxy M87 are whirling unusually fast about the galaxy’s center. Most astronomers believe that the large concentration of mass at the galaxy’s center is a black hole whose gravity is causing the gas to whirl. A few skeptics have argued that the concentration of mass necessary to explain the speed of the whirling gas is not necessarily a black hole: the concentration in M87 might be a cluster of a billion or so dim stars. The same hypothesis might have been applied to the galaxy NGC 4258, but the notion of such a cluster’s existing in NGC 4258 was severely undermined when astronomers measured the speed of a ring of dust and gas rotating close to the galaxy’s center. From its speed, they calculated that the core’s density is more than 40 times the density estimated for any other galaxy. If the center of NGC 4258 were a star cluster, the stars would be so closely spaced that collisions between individual stars would have long ago torn the cluster apart.

1. The skeptics mentioned in the first paragraph would be most likely to agree with the astronomers mentioned in line 13 about which of the following statements concerning the galaxy M87?(A) The speed of the gas whirling around the center of M87 is caused by a dense object that is not a black hole.(B) The concentration of mass at the center of M87 is probably a large cluster of dim stars.(C) The presence of a black hole at the center of M87 is the most likely explanation for the speed of the gas whirling about the galaxy’s core.(D) The speed of the gas whirling around the center of M87 is caused by a large concentration of mass at the core of M87.(E) The gravitational influence of a star cluster would not be strong enough to account for the speed of the gas whirling around the core of M87.2. The passage asserts which of the following about the existence of black holes?(A) Astronomers first speculated about the existence of black holes when they observed gas whirling around the center of a particular galaxy.(B) Evidence used to argue for the existence of black holes is indirect, coming from their presumed effects on other astronomical bodies.(C) Recent observations of certain astronomical bodies have offered proof.(D) A considerable body of evidence suggests the existence of black holes, even though their behavior is not completely consistent with the laws of physics.(E) Many astronomers are skeptical about certain recent evidence that has been used to argue for the existence of black holes.3. Which of the following, if true, would most clearly undermine the possible explanation for the whirling gas in M87 that is mentioned in the last sentence of the first paragraph?(A) The stars in a star cluster at the center of M87 could exert a strong gravitational force without tearing the cluster apart.(B) A cluster of stars at the center would preclude the existence of certain other astronomical phenomena that have been observed at the center of M87.(C) The stars within many existing galaxies, such as NGC 4258, are more closely spaced than are the stars within the core of M87.(D) Only one other galaxy has been observed to contain gas clouds whirling about its center as they do about the core of M87.(E) The gravitational force of a cluster of a billion or so dim stars would be sufficient to cause a whirling ring of gas and dust to collect around the center of a galaxy.4. The passage is primarily concerned with(A) explaining why a particular phenomenon is so rare(B) criticizing a method used to gather data about a natural phenomenon(C) considering possible instances of a particular phenomenon(D) distinguishing among several different kinds of natural phenomena(E) questioning a widely accepted explanation for an unusual phenomenon

Explanation:

The black holes are formed when a sun dies.

The sun blasts and it forms a black hole which is in visible to the naked eye.

When something is pulled inside a black hole, the matter is squeezed.

Paradise Lost, Book X, 124-162

Adam sore beset repli'd.
O Heav'n! in evil strait this day I stand125
Before my Judge, either to undergoe
My self the total Crime, or to accuse
My other self, the partner of my life;
Whose failing, while her Faith to me remaines,
I should conceal, and not expose to blame130
By my complaint; but strict necessitie
Subdues me, and calamitous constraint
Least on my head both sin and punishment,
However insupportable, be all
Devolv'd; though should I hold my peace, yet thou135
Wouldst easily detect what I conceale.
This Woman whom thou mad'st to be my help,
And gav'st me as thy perfet gift, so good,
So fit, so acceptable, so Divine,
That from her hand I could suspect no ill,140
And what she did, whatever in it self,
Her doing seem'd to justifie the deed;
Shee gave me of the Tree, and I did eate.

To whom the sovran Presence thus repli'd.
Was shee thy God, that her thou didst obey145
Before his voice, or was shee made thy guide,
Superior, or but equal, that to her
Thou did'st resigne thy Manhood, and the Place
Wherein God set thee above her made of thee,
And for thee, whose perfection farr excell'd150
Hers in all real dignitie: Adornd

Thy Love, not thy Subjection, and her Gifts
Were such as under Government well seem'd,
Unseemly to beare rule, which was thy part155
And person, hadst thou known thy self aright.

So having said, he thus to Eve in few:
Say Woman, what is this which thou hast done?

To whom sad Eve with shame nigh overwhelm'd,

Scene III of Doctor Faustus

FAUST. How comes it then that thou art out of hell?

MEPHISTOPHILIS. Why this is hell, nor am I out of it.
Think’st thou that I who saw the face of God,
And tasted the eternal joys of Heaven,
Am not tormented with ten thousand hells,
In being depriv’d of everlasting bliss?
O Faustus! leave these frivolous demands,
Which strike a terror to my fainting soul.

FAUST. What, is great Mephistophilis so passionate
For being depriv’d of the joys of Heaven?
Learn thou of Faustus manly fortitude,
And scorn those joys thou never shalt possess.


Which line from the other scenes of the play provides the greatest FAUST.



1-FAUST. When I behold the heavens, then I repent / And curse thee, wicked Mephistophilis, / Because thou hast deprived me of those joys.

2-FAUST. Well, I’m content to compass then some sport, / And by their folly make us merriment. / Then charm me, [Mephistophilis,] that I / May be invisible, to do what I please / Unseen of any whilst I stay in Rome.

3-FAUST. Where art thou, Faustus? Wretch, what hast thou done! / Hell claims his right and with a roaring voice / Says “Faustus, come, thine hour is almost come!” / And Faustus will now come to do thee right!

4-FAUST. My God, my God! Look not so fierce on me! / Adders and serpents, let me breathe awhile! / Ugly Hell, gape not! Come not Lucifer! / I’ll burn my books!—O Mephistophilis!

Prometheus

by Lord Byron

In this poem, the speaker commends Prometheus for his silent suffering as he endures the cruel punishment inflicted on him by Zeus, king of the Greek gods. Prometheus defied Zeus by helping humankind by gifting them with his knowledge and kindness, as well as the ability to make fire. Zeus was willing to pardon Prometheus if only he revealed his prophesy about Zeus’s fate. But Prometheus refused for many years. Byron portrays Prometheus as a symbol of humankind, part divine and part mortal, destined to suffer in life, but to learn and to triumph from that suffering.

Titan! to whose immortal eyes

The sufferings of mortality,

Seen in their sad reality,

Were not as things that gods despise;

What was thy pity's recompense?

A silent suffering, and intense;

The rock, the vulture, and the chain,

All that the proud can feel of pain,

The agony they do not show,

The suffocating sense of woe,

Which speaks but in its loneliness,

And then is jealous lest the sky

Should have a listener, nor will sigh

Until its voice is echoless.



Titan! to thee the strife was given

Between the suffering and the will,

Which torture where they cannot kill;

And the inexorable Heaven,

And the deaf tyranny of Fate,

The ruling principle of Hate,

Which for its pleasure doth create

The things it may annihilate,

Refus'd thee even the boon to die:

The wretched gift Eternity

Was thine—and thou hast borne it well.

All that the Thunderer wrung from thee

Was but the menace which flung back

On him the torments of thy rack;

The fate thou didst so well foresee,

But would not to appease him tell;

And in thy Silence was his Sentence,

And in his Soul a vain repentance,

And evil dread so ill dissembled,

That in his hand the lightnings trembled.



Thy Godlike crime was to be kind,

To render with thy precepts less

The sum of human wretchedness,

And strengthen Man with his own mind;

But baffled as thou wert from high,

Still in thy patient energy,

In the endurance, and repulse

Of thine impenetrable Spirit,

Which Earth and Heaven could not convulse,

A mighty lesson we inherit:

Thou art a symbol and a sign

To Mortals of their fate and force;

Like thee, Man is in part divine,

A troubled stream from a pure source;

And Man in portions can foresee

His own funereal destiny;

His wretchedness, and his resistance,

And his sad unallied existence:

To which his Spirit may oppose

Itself—and equal to all woes,

And a firm will, and a deep sense,

Which even in torture can descry

Its own concenter'd recompense,

Triumphant where it dares defy,

And making Death a Victory.

How does Byron’s poem show the influence of the myth of Prometheus?

1)Both texts emphasize the strength of mortals over that of the gods.

2) Both texts explain how the reconciliation of Zeus and Prometheus benefited humankind.

3)Both texts develop the idea that Prometheus is a martyr.

4)Both texts give the idea that there is a limit to the suffering an individual can endure.

The Scientist Experiments

by Stacy Lewis



(1) Scientists study the world around us. (2) One way that scientists do their jobs is by conducting experiments. (3) The experiments that scientists conduct are like tests that they perform. (4) Experiments help scientists learn how things happen in our world and why things happen in our world. (5) For example, a botanist, a type of scientist who studies plants, a botanist would perform experiments related to plants.

(6) Here is an example of a basic, meaningful experiment that a botanist might conduct. (7) The materials required are a seed, a pot of soil, and water. (8) First, the scientist plants a seed in the soil. (9) She then places the pot on a window sill, or a similarly sunny place where it can soak in the sun. (10) She waters the seed every day, watches for changes. (11) And then she dutifully records what happens. (12) After thirty days, she measures both the plant's height and weight, as well as also measuring the number of leaves it has grown.

(13) Next, she repeats the same steps with another seed, excepting that she only waters the second seed once a week this time. (14) Again, she takes records of the plant's growth and makes the same measurements. (15) Then she compares her results, hoping to figure out the impact of daily watering on plants. (16) Does regular watering make plants healthy and tall, or does it not matter? (17) Her results can help to reveal the answers to such queries.
