The progress of astronomy has always been closely associated with the development and application of mechanical processes and skill. Before the seventeenth century, the size of the planets could not be measured, the satellites of the planets except the Earth’s moon were unknown, the phases of Mercury and Venus were merely conjectured, and accurate positions of the sun, moon, and planets among the stars, and of the stars among themselves, were impossible all because there were no telescopes. More than a half century elapsed after the invention of the telescope before Picard combined it with a graduated circle in such a way that the measurement of angles was greatly improved. Then arose the necessity for accurate time. Although Galileo had learned the principles governing the pendulum, astronomy had to wait for the mechanical genius of Huygens before a satisfactory clock was invented around 1657.
Nearly all the large reflecting telescopes ever built were constructed by astronomers who possessed great facility in practical mechanics. The rapid and significant advances in nearly all departments of astronomy in the past century would not have been possible except through the skill and patience of glassmakers, opticians, and engineers. The principles of spectrum analysis as formulated by Kirchho allowed for the discovery of the elements composing every heavenly body. The deftness of Wollaston showed that light could not be analyzed unless it first passed through a very narrow slit. Even in our modern day the power of the telescope and spectroscope has been vastly extended by the optical skill and mechanical dexterity of individuals such as Rowland, Hastings and Brashear, all Americans.
An observatory site should have a fairly unobstructed horizon, as much freedom from cloud as possible, good foundations for the instruments, and a very steady atmosphere. To understand the necessity of a steady atmosphere, look at some distant outdoor object through a window on a hot summer day. The object appears blurry and wavering. Similarly, currents of warm air continually rise from the earth to upper regions of the atmosphere, and colder air  comes down and rushes underneath. Although these atmospheric movements are often invisible to the eye, their effect is plainly visible in the telescope as a blurry distortion. In order for an ideally-designed telescope to perform perfectly, it must be located in a perfect atmosphere. Otherwise its full power cannot be employed. All hindrances of atmosphere are most advantageously avoided in arid or desert regions of the globe, at elevations of 3000 to 10,000 feet above sea level. Higher mountains have as yet been only partially investigated, and it is not known whether difficulties of occupying them permanently would more than counterbalance the gain which greater elevation would afford.
It can be inferred from the passage that
  • a)
    without telescopes, accurate readings of the positions of celestial bodies are currently impossible. 
  • b)
    even the most superlatively designed telescope possibly  functions below its fully ability at 2000 feet above sea level.
  • c)
    almost all the great telescopes were built by astronomers who possessed excellent knowledge of practical mechanics. 
  • d)
    the atmospheric movements that cause blurry distortion in a telescope can never be detected by the naked eye.
  • e)
    a telescope requires an observatory site in order to function.

Passage Analysis
 
Pre-Thinking
This is an Inference question. This is an open-ended inference question, and it is difficult to come up with your own pre-phrased answer before examining the answer choices. The correct inference will follow closely from what is implied in the passage, and will not be contradicted by any explicit details. 
Answer Choices
A
without telescopes, accurate readings of the positions of celestial bodies are currently impossible. 
Incorrect: Out of Scope
Although the passage does state that accurate positions of the sun, moon, and planets among the stars, and of the stars among themselves, were impossible all because there were no telescopes, it gives us no information to state that presently there are no other devices that are capable of the same. 
B
even the most superlatively designed telescope possibly  functions below its fully ability at 2000 feet above sea level.
Correct
This statement can be derived from the following two statements in the passage:
(1)  In order for an ideally-designed telescope to perform perfectly, it must be located in a perfect atmosphere.
(2)  All hindrances of atmosphere are most advantageously avoided in arid or desert regions of the globe, at elevations of 3000 to 10,000 feet above sea level.
C
almost all the great telescopes were built by astronomers who possessed excellent knowledge of practical mechanics. 
Incorrect: Inconsistent
The passage mentions that nearly all the large reflecting telescopes ever built were constructed by astronomers who possessed great facility in practical mechanics.  By no means does “large” translate into “great.”
D
the atmospheric movements that cause blurry distortion in a telescope can never be detected by the naked eye.
Incorrect: Out of Scope
While the passage does say that these atmospheric movements are often invisible to the eye, their effect is plainly visible in the telescope as a blurry distortion, the word “never” here is not justified.
E
a telescope requires an observatory site in order to function. 
Incorrect: Out of Scope
While the final paragraph does impress upon the reader the importance of an observatory site to a telescope’s accuracy, it does not go so far as to imply that a telescope is non-functional without one. Its accuracy may be diminished, but presumably it could still “function.”

Comparable worth, as a standard applied to eliminate inequities in pay, insists that the values of certain tasks performed in dissimilar jobs can be compared. In the last decade, this approach has become a critical social policy issue, as large numbers of private-sector firms and industries as well as federal, state, and local governmental entities have adopted comparable worth policies or begun to consider doing so.This widespread institutional awareness of comparable worth indicates increased public awareness that pay inequities—that is, situations in which pay is not "fair" because it does not reflect the true value of a job—exist in the labor market. However, the question still remains: have the gains already made in pay equity under comparable worth principles been of a precedent-setting nature or are they mostly transitory, a function of concessions made by employers to mislead female employees into believing that they have made long-term pay equity gains?Comparable worth pay adjustments are indeed precedent-setting. Because of the principles driving them, other mandates that can be applied to reduce or eliminate unjustified pay gaps between male and female workers have not remedied perceived pay inequities satisfactorily for the litigants in cases in which men and women hold different jobs. But whenever comparable worth principles are applied to pay schedules, perceived unjustified pay differences are eliminated. In this sense then, comparable worth is more comprehensive than other mandates, such as the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964. Neither compares tasks in dissimilar jobs (that is, jobs across occupational categories) in an effort to determine whether or not what is necessary to perform these tasks—know-how, problem-solving, and accountability—can be quantified in terms of its dollar value to the employer. Comparable worth, on the other hand, takes as its premise that certain tasks in dissimilar jobs may require a similar amount of training, effort, and skill; may carry similar responsibility; may be carried on in an environment having a similar impact upon the worker; and may have a similar dollar value to the employer.It can be inferred from the passage that application of "other mandates" (see highlighted text) would be unlikely to result in an outcome satisfactory to the female employees in which of the following situations?I. Males employed as long-distance truck drivers for a furniture company make $3.50 more per hour than do females with comparable job experience employed in the same capacity.II. Women working in the office of a cement company contend that their jobs are as demanding and valuable as those of the men working in the cement factory, but the women are paid much less per hour.III. A law firm employs both male and female paralegals with the same educational and career backgrounds, but the starting salary for male paralegals is $5,000 more than for female paralegals.

The following emails come from the Public Relations division of a largenon-profit organization.Hello Gloria!We have to choose a caterer for the upcoming gala. Two underconsideration are DoxySource and BrightRight. Although DoxySource hasdelivered satisfactory service in the past, our First Annual Sponsors Galapromises to be the largest event we have ever hosted, and BrightRight isknown for large event planning and production. However, I’d like moreinformation before switching from a tried and true contractor. Also, I’d liketo consider how to justify any over-budget costs from using BrightRight, ifthat comes up. I am committed to using only one provider. Please work up acomparison of costs of services and rentals for BrightRight andDoxySource. We require: tables, audio, food, and a punch fountain orfountains (a dessert fountain would be a lovely addition). Our budget is$6,000.00, and we plan for a maximum of 400 people.Thanks!Evelyn SchottGala CoordinatorHello Evelyn,I’ve broken out the data in the following chart:BrightRight offers packages that are generally more elegant andcomprehensive, and more expensive. For instance, we can choose a singlefull meal set, such as “The Greek Feast,” for the entire gala. Using DoxySource, while more economical and flexible in the catering, does meanmore hands-on involvement on our end.The biggest price difference comes in the audio systems. BrightRight,which consistently hosts events with attendance of several hundreds, offerscomplex systems that include lights and sound effects, in addition to highdefinitionaudio reproduction. DoxySource offers two standard, large publicaddress systems. I am not sure whether the Gala will need all the flash andsizzle of the high-end sound system; but the projected attendance is abovethe recommended usage for DoxySource’s P.A. systems. Due to electricalconcerns, we can only have one P.A. system at the gala.Gloria WelchAdministrative Assistant, Public RelationsQ.Based on the information in the communications above, and assuming themaximum number of guests, which of the following must be true?If the coordinator uses DoxySource and orders oneappetizer, one entrée and one dessert per person, then the table costswill be approximately 16.6% of the food costs.

Higher mountains have as yet been only partially investigated, and it is not known whether difficulties of occupying them permanently would more than counterbalance the gain which greater elevation would afford.It can be inferred from the passage thata)without telescopes, accurate readings of the positions of celestial bodies are currently impossible.b)even the most superlatively designed telescope possibly functions below its fully ability at 2000 feet above sea level.c)almost all the great telescopes were built by astronomers who possessed excellent knowledge of practical mechanics.d)the atmospheric movements that cause blurry distortion in a telescope can never be detected by the naked eye.e)a telescope requires an observatory site in order to function.Correct answer is option 'B'. Can you explain this answer? defined & explained in the simplest way possible. Besides giving the explanation of The progress of astronomy has always been closely associated with the development and application of mechanical processes and skill. Before the seventeenth century, the size of the planets could not be measured, the satellites of the planets except the Earth’s moon were unknown, the phases of Mercury and Venus were merely conjectured, and accurate positions of the sun, moon, and planets among the stars, and of the stars among themselves, were impossible all because there were no telescopes. More than a half century elapsed after the invention of the telescope before Picard combined it with a graduated circle in such a way that the measurement of angles was greatly improved. Then arose the necessity for accurate time. Although Galileo had learned the principles governing the pendulum, astronomy had to wait for the mechanical genius of Huygens before a satisfactory clock was invented around 1657.Nearly all the large reflecting telescopes ever built were constructed by astronomers who possessed great facility in practical mechanics. The rapid and significant advances in nearly all departments of astronomy in the past century would not have been possible except through the skill and patience of glassmakers, opticians, and engineers. The principles of spectrum analysis as formulated by Kirchho allowed for the discovery of the elements composing every heavenly body. The deftness of Wollaston showed that light could not be analyzed unless it first passed through a very narrow slit. Even in our modern day the power of the telescope and spectroscope has been vastly extended by the optical skill and mechanical dexterity of individuals such as Rowland, Hastings and Brashear, all Americans.An observatory site should have a fairly unobstructed horizon, as much freedom from cloud as possible, good foundations for the instruments, and a very steady atmosphere. To understand the necessity of a steady atmosphere, look at some distant outdoor object through a window on a hot summer day. The object appears blurry and wavering. Similarly, currents of warm air continually rise from the earth to upper regions of the atmosphere, and colder air comes down and rushes underneath. Although these atmospheric movements are often invisible to the eye, their effect is plainly visible in the telescope as a blurry distortion.
