Arrange sentences A, B, C and D between sentences 1 and 6 to form a logical sequence of the six sentences.
1. Security inks exploit the same principle that causes the vivid and constantly changing colours of a film of oil on water.
A. When two rays of light meet each other after being reflected from these different surfaces, they have each travelled slightly different distances.
B. The key is that the light is bouncing off two surface, that of the oil and that of the water layer below it.
C. The distance the two rays determines which wavelengths, and hence colours, interfere constructively and look bright.
D. Because light is an electromagnetic wave, the peaks and troughs of each ray then interfere either constructively, to appear bright, or destructively, to appear dim.
6. Since the distance the rays travel changes with the angle as you look at the surface, different colours look bright from different viewing angles.
  • a)
    ABCD
  • b)
    BADC
  • c)
    BDAC
  • d)
    DCAB
Correct answer is option 'B'. Can you explain this answer?

Sentence B is the first choice as it explains the principle given in sentence number 1, this is followed by A which further clarifies it and then by D, which is again a further clarification of the principle and last is C, which is the logical conclusion of the principle.
Hence, the correct option is (b).

Arrange sentences A, B, C and D between sentences 1 and 6 to form a l...
Explanation:

Understanding the Principle of Security Inks:
- Security inks work on the principle of exploiting the same phenomenon seen in the changing colors of a film of oil on water.

Explanation of Sentence A:
- Sentence A explains that when two rays of light meet after being reflected from different surfaces, they have traveled different distances.

Explanation of Sentence B:
- Sentence B elaborates on the key concept that light bounces off two surfaces - the oil and the water layer below it.

Explanation of Sentence D:
- Sentence D further explains that since light behaves as an electromagnetic wave, the peaks and troughs of each ray interfere constructively or destructively, affecting the appearance of the colors.

Explanation of Sentence C:
- Sentence C clarifies that the distance the two rays travel determines which wavelengths and colors interfere constructively and appear bright.

Conclusion - Sentence 6:
- Sentence 6 ties everything together by stating that the distance the rays travel changes with the viewing angle, causing different colors to appear bright from different angles.
Therefore, the correct sequence to form a logical flow of information is option 'B' (BADC).

Directions: The passage below is followed by some questions based on its content. Answer the questions on the basis of what is stated or implied in the passage.Our digital world depends on the interconnectivity between wireless devices, often battery-free with no direct power supply. Such devices include wireless passive sensors, designed to receive and respond to signals from the environment. These devices can be powered by electromagnetic waves, provided their antenna can efficiently convert waves to energy. When Alexander Graham Bell made the first-ever phone call in 1876, calling his assistant to meet him, the connectivity of todays world would have been well beyond his wildest dreams. Perhaps even in the late 1980s and early 1990s, when the internet as we know it started to emerge, the digital world we have since built would have been unimaginable. Today, we dont just use technology to communicate with each other: we are also finding ways to make devices communicate between themselves to allow us to control our environments. The Internet of Things, as it is now called, is the combination of the immense web of sensors, devices, apps, and other technology that are connected and sharing information between them.To control our world, however, we need to be able to interconnect many devices which, for ease of installation and pleasing design, are usually wireless, including no power supply cables. For environmental reasons, it is also beneficial that these devices are battery-free. Battery-free devices can instead be powered by the electromagnetic waves they receive from the powered devices they are connected to. With the right equipment, the electromagnetic waves sent by the Wi-Fi router could be enough to supply the energy needed to power the motion sensor. Devices whose function is to detect and respond to physical signals from the surrounding environment are called passive sensors. The ability of a passive sensor to harvest energy from the environment depends heavily on the ability of its antenna – which receives electromagnetic waves – to efficiently turn waves into electricity that can power it. As such, a crucial part of improving this remote powering technology involves making the rectifier (the part of the antenna responsible for converting waves to power) work as efficiently as possible.The rectifier performance can be measured in terms of its voltage conversion efficiency, or its power conversion efficiency, where voltage refers to an electrical potential, and power here refers to the rate at which electrical energy is transferred through an electrical circuit. However, these two quantities are closely interlinked in complex ways, to such an extent that optimising one of these parameters is often done at the expense of the other, and it is not possible to optimise both parameters simultaneously. Dominik Mair and his colleagues at the University of Innsbruck in Austria, have shown in a recent publication that using either voltage or power conversion efficiency as measures of rectifier performance is not feasible. Instead, the team demonstrated that the concept of a mean conversion efficiency (the average of the voltage and power conversion efficiencies) allows optimisation algorithms to find optimum rectifier circuit designs much quicker. Not only that, but the resulting designs also show superior overall performance when compared to previous ones, even with very low power from incoming waves. The growing demand for intelligent devices that are interconnected with each other, allowing us to control our environment, is pushing the development of wireless, battery-free sensors which can gather information and even make decisions or control actuators.Q.Why does the author state that rectifiers should work as efficiently as possible to improve remote powering technology?

Each of the questions below contains a paragraph followed by alternative summaries. Choose the option that best captures the essence of the paragraph.Thousands of officials from all over the world met for two weeks of difficult talks in Bonn under the United Nations climate convention. But they were conscious that even more difficult and probably more important negotiations were under way in Beijing. Americas most senior climate-change officials were meeting their Chinese counterparts. The two countries are by far the worlds biggest emitters of greenhouse gases. They will determine whether a worthwhile global treaty to limit emissions can be concluded as planned in Copenhagen in December. The treaty is to replace the Kyoto protocol, which expires in 2012. Some 180 countries will take part in the negotiations, but many feel that, on this issue more than any other, China and America make up a G2 that determines the global post-Kyoto agenda.1. The United Nations climate convention may not be able to determine the global post-Kyoto agenda on green house gases unless China and America jointly ratifies it.2. In 2012, China and America, the two biggest emitters of green house gases have the potential to determine the global post-Kyoto agenda to limit emissions.3. At the next United Nations climate convention, China and America, the two biggest emitters of green house gases, will determine the global post-Kyoto agenda to limit emissions.4. At the next United Nations climate convention, China and America, the two biggest emitters of green house gases, will determine the global post-Kyoto agenda to limit emissions, overriding 180 other nations.
