Working at Bell Labs in Holmdel, New Jersey, in 1964, Arno Penzias and Robert Wilson were experimenting with a supersensitive, 6 meters (20 ft) horn antenna originally built to detect radio waves bounced off echo balloon satellites. To measure these faint radio waves, they had to eliminate all recognizable interference from their receiver. They removed the effects of radar and radio broadcasting, and suppressed interference from the heat in the receiver itself by cooling it with liquid helium to -269 C, only 4 C above absolute zero.When Penzias and Wilson reduced their data they found a low, steady, mysterious noise that persisted in their receiver. This residual noise was 100 times more intense than they had expected, was evenly spread over the sky, and was present day and night. They were certain that the radiation they detected on a wavelength of 7.35 centimeters did not come from the Earth, the Sun, or our galaxy. After thoroughly checking their equipment, removing some pigeons nesting in the antenna and cleaning out the accumulated droppings, the noise remained. Both concluded that this noise was coming from outside our own galaxy although they were not aware of any radio source that would account for it.At that same time, Robert H. Dicke, Jim Peebles, and David Wilkinson, astrophysicists at Princeton University just 60 km (40 miles) away, were preparing to search for microwave radiation in this region of the spectrum. Dicke and his colleagues reasoned that the Big Bang must have scattered not only the matter thatcondensed into galaxies but also must have released a tremendous blast of radiation. With the proper instrumentation, this radiation should be detectable.When a friend (Bernard F. Burke, Prof, of Physics at MIT) told Penzias about a preprint paper he had seen by Jim Peebles on the possibility of finding radiation left over from an explosion that filled the universe at the beginning of its existence, Penzias and Wilson began to realize the significance of their discovery. The characteristics of the radiation detected by Penzias and Wilson fit exactly the radiation predicted by Robert H. Dicke and his colleagues at Princeton University. Penzias called Dicke at Princeton, who immediately sent him a copy of the still-unpublished Peebles paper. Penzias read the paper and called Dicke again and invited him to Bell Labs to look at the Horn Antenna and listen to the background noise. Robert Dicke, P. J. E. Peebles, P. G. Roll and D. T. Wilkinson interpreted this radiation as a signature of the Big Bang.To avoid potential conflict, they decided to publish their results jointly. Two notes were rushed to the Astrophysical Journal Letters. In the first, Dicke and his associates outlined the importance of cosmic background radiation as substantiation of the Big Bang Theory. In a second note, jointly signed by Penzias and Wilson titled, A Measurement of Excess Antenna Temperature at 4080 Megacycles per Second, they noted the existence of the residual background noise and attributed a possible explanation to that given by Dicke in his companion letter.Q.Choose an appropriate title for the passage from the options given below:a)Microwave Radiation and its connection to the Big Bang Theoryb)The Discovery of Cosmic Background Radiation by Penzias and Wilsonc)The residue left behind by the Big Bang Theoryd)Penzias and Wilsons journey towards a Nobel PrizeCorrect answer is option 'B'.

Option 1 provides a partial answer. The scientists and their discovery are equally important elements of the passage. Option 3 is more narrow than option 1.
Option 4 can be eliminated as the passage doesn’t mention Nobel Prize anywhere.
Option 2 is correct because the passage reads like a story; it takes us through the various elements that came together for the discovery of a phenomenon as monumental as cosmic background radiation, and the two main architects whose efforts led to the discovery - Penzias and Wilson. Hence, the correct answer is option 2.

Question: Analyse the following passage and provide an appropriate answer for the questions that follow.Formation of focal brand expectations is a well-accepted part of the pre-purchase choice process. However, whether these same expectations are the standard for post-choice performance evaluation has been questioned. There is very little theoretical justification for consumers using focal brand expectations to judge performance after purchase. Customer satisfaction/dissatisfaction is more likely to be determined by how well a consumer perceives that focal brand performance fulfils needs, wants, or desires.Importantly, there is no necessary relationship between prepurchase focal brand expectations and the performance required to meet those wants. Thus, consumers are very likely to use other kinds of performance standards in the post-purchase evaluation. Consumers are likely to rely on standards that reflect the performance a consumer believes a focal brand should provide to meet needs/wants. To distinguish these standards from the usual expectations concept, we call them "experience-based norms." These norms have two important characteristics: (1) they reflect desired performance in meeting needs/wants and (2) they are constrained by the performance consumers believe is possible as indicated by the performance of known brands. The second characteristic requires elaboration. Though consumers may imagine some abstract ideal performance that a brand should provide, they also have concrete experiences with various real brands and their performance. Because consumers are more likely to think in concrete rather than abstract terms, experience with real brands should set limits on the performance a consumer believes the focal brand should provide. Consumers may derive a norm from experience with known brands in at least two different ways. First, the norm might be the typical performance of a particular brand - e.g., a consumer's most preferred brand, a popular brand, or last-purchased brand.Importantly, this brand may not be the focal brand. For example, when evaluating the dining experience in a new restaurant, a consumer may apply a norm that is the typical performance of another, favourite restaurant. Interestingly, focal brand expectations may correspond to this norm, but only if the focal brand is also the brand from which the standard is derived, such as when a consumer dines in his or her favourite restaurant. In all other cases, the norm is necessarily different from expectations because the norm is derived from experience with a different brand. A second possibility is that the norm might be an average performance a consumer believes is typical of a group of similar brands — a product-based norm. This kind of norm may be reasonable when no one brand stands out in the consumer's mind and the consumer has experience with many brands. In general, the experience-based norms concept is significant because it suggests that past research may have attached unwarranted importance to focal brand expectations as the standard of performance influencing feelings of satisfaction.Which of the following statements, if true, would contradict the second characteristic of “experience-based norms”?

Chauvinism, in its original meaning, is an exaggerated patriotism and a belligerent belief in national superiority and glory. Its eponym is a seemingly apocryphal French soldier Nicholas Chauvin. By extension, it has come to include an extreme and unreasoning partisanship on behalf of any group to which one belongs, especially when the partisanship includes malice and hatred towards rival groups. In our enlightened times, when most forms of chauvinism have been abandoned, at least in theory, by those who consider themselves progressive, Western ethics still appears to retain, at its very heart, a fundamental form of chauvinism, namely, human chauvinism. For both popular Western thought and most Western ethical theories assume that both value and morality can ultimately be reduced to matters of interest or concern to the class of humans.Chauvinists are always anxious to stress distinguishing points between the privileged class and those outside it and there is no lack of characteristics which distinguish humans from non-humans, at least functioning healthy adult ones. The point is that these distinctions usually do not warrant the sort of radically inferior treatment for which they are proposed as a rationale. On the basis of the characteristics, then, the proposed radical difference in treatment between the privileged and non-privileged class and the purely instrumental treatment of the non-privileged class, must be warranted, that is, the distinguishing characteristics must be able to carry the moral superstructure placed upon them.Q. On the basis of this passage, what could the term male chauvinism most likely mean?

They removed the effects of radar and radio broadcasting, and suppressed interference from the heat in the receiver itself by cooling it with liquid helium to -269 °C, only 4 °C above absolute zero.When Penzias and Wilson reduced their data they found a low, steady, mysterious noise that persisted in their receiver. This residual noise was 100 times more intense than they had expected, was evenly spread over the sky, and was present day and night. They were certain that the radiation they detected on a wavelength of 7.35 centimeters did not come from the Earth, the Sun, or our galaxy. After thoroughly checking their equipment, removing some pigeons nesting in the antenna and cleaning out the accumulated droppings, the noise remained. Both concluded that this noise was coming from outside our own galaxy although they were not aware of any radio source that would account for it.At that same time, Robert H. Dicke, Jim Peebles, and David Wilkinson, astrophysicists at Princeton University just 60 km (40 miles) away, were preparing to search for microwave radiation in this region of the spectrum. Dicke and his colleagues reasoned that the Big Bang must have scattered not only the matter thatcondensed into galaxies but also must have released a tremendous blast of radiation. With the proper instrumentation, this radiation should be detectable.When a friend (Bernard F. Burke, Prof, of Physics at MIT) told Penzias about a preprint paper he had seen by Jim Peebles on the possibility of finding radiation left over from an explosion that filled the universe at the beginning of its existence, Penzias and Wilson began to realize the significance of their discovery. The characteristics of the radiation detected by Penzias and Wilson fit exactly the radiation predicted by Robert H. Dicke and his colleagues at Princeton University. Penzias called Dicke at Princeton, who immediately sent him a copy of the still-unpublished Peebles paper. Penzias read the paper and called Dicke again and invited him to Bell Labs to look at the Horn Antenna and listen to the background noise. Robert Dicke, P. J. E. Peebles, P. G. Roll and D. T. Wilkinson interpreted this radiation as a signature of the Big Bang.To avoid potential conflict, they decided to publish their results jointly. Two notes were rushed to the Astrophysical Journal Letters. In the first, Dicke and his associates outlined the importance of cosmic background radiation as substantiation of the Big Bang Theory. In a second note, jointly signed by Penzias and Wilson titled, “A Measurement of Excess Antenna Temperature at 4080 Megacycles per Second,” they noted the existence of the residual background noise and attributed a possible explanation to that given by Dicke in his companion letter.Q.Choose an appropriate title for the passage from the options given below:a)Microwave Radiation and its connection to the Big Bang Theoryb)The Discovery of Cosmic Background Radiation by Penzias and Wilsonc)The residue left behind by the Big Bang Theoryd)Penzias and Wilson’s journey towards a Nobel PrizeCorrect answer is option 'B'.
