CAT Question of the Day The question below contains a paragraph followed by alternative summaries. Choose the option that best captures the essence of the paragraph.
The device paradigm can be illustrated through comparison of a wood-burning stove, a "thing", versus the central heating system, a "device". The central heating system derives its technological qualities from the fact that it is easy to use, safe to operate, ubiquitous, and the user generally needs to understand little of the way in which the system operates. The wood-burning stove, on the other hand, takes more skill in its operation in that it requires wood to be chopped beforehand, and prepared for use in the stove. The act of lighting the fire is not safe enough to be done by, for example, a child, and requires a degree of vigilance over its operation. The stove is not ubiquitous because it orients the senses and commands attention for its user throughout the time of its operation. It also requires some knowledge of how the stove works in order to make successful use of it.
| OPTIONS | | |  | 1) | The device paradigm explains the hidden power of technological devices operating in our world of which the user may have no knowledge versus instruments that require the user to be skilled to make successful use of them. | | | 2) | The comparison of a wood-burning stove which requires certain level of knowledge and skill to operate and a central heating system of which the user requires little knowledge illustrates the concept of device paradigm. | | | 3) | The device paradigm is best understood through the example of a wooden stove that requires special knowledge and skill to operate when it is compared with the central heating system that requires little or no knowledge. | | | 4) | The technological qualities of a central heating system which requires the user to understand little of how the system operates best illustrates the concept of device paradigm. | | | 5) | The technological qualities of a central heating system which requires the user to understand little about its operation and the wood-burning stove illustrate the concept of device paradigm. |
Tip of the Day The area of any triangle is directly proportional to the square of any of its linear attributes - side, median, altitude. This property can be used to solve questions based on similar triangles faster. Last year's Question of the day (05-Apr-11) Paleobiogeography also helps constrain hypotheses on the timing of biogeographic events such as vicariance and geodispersal, and provides unique information on the formation of regional biotas. For example, data from species-level phylogenetic and biogeographic studies tell us that the Amazonian fish fauna accumulated incrementally over a period of tens of millions of years, principally by means of allopatric speciation, and in an arena extending over most of the area of tropical South America (Albert & Reis 2011). In other words, unlike some of the well-known insular faunas (Galapagos finches, Hawaiian drosophilid flies, African rift lake cichlids), the species-rich Amazonian ichthyofauna is not the result of recent adaptive radiations. For freshwater organisms, landscapes are divided naturally into discrete drainage basins by watersheds, episodically isolated and reunited by erosional hydrodynamics. In regions like the Amazon Basin with an exceptionally low (flat) topographic relief, the many waterways have had a highly reticulated history over geological time.
Which of the following sentences can be concluded from the passage?
| OPTIONS | | | | | 1) | The only difference between ichthyofaunas and Galapago finches is that the former is episodically isolated. | | | 2) | Allopatric speciation for more than a million years was primarily responsible for Amazonian fish fauna. | | | 3) | Vicariance is a bio-geographic event that provides unique information on the formation of regional biotas. | | | 4) | Recent adaptive radiations are responsible for the creation of the Amazonian fish fauna. | | | 5) | Erosional hydrodynamics and watersheds play their part in dividing freshwater organisms. |
