Explanation

Colossal squid have the biggest eyes of any living creature. This is because their enormous eyes are adapted to detect large prey in the dimly lit deep-sea environment where they live, and are said to be up to 27 cm in diameter, giving them the largest eyes of any animal. The QuizMaster of AnsweringExams.Com suggests remembering this fact by associating the colossal squid’s huge eyes with the largest diameter, 27, which is also the number of bones in the human hand, making it a memorable and unusual fact to recall. Other options are incorrect because they do not have the same level of adaptation to deep-sea environments, and therefore do not require such large eyes to survive.

Software is the term used to describe the programs run by a computer, as opposed to the hardware. This answer is correct because software refers to the set of instructions that a computer’s hardware executes, and it includes operating systems, applications, and other types of programs. The QuizMaster of AnsweringExams.Com suggests associating the term software with the idea that it is the “soft” part of a computer system, as opposed to the physical hardware, and remembering that the first software program was written by Ada Lovelace in 1843. The other options are incorrect because they do not accurately describe the concept of programs run by a computer, and they are either too narrow or too broad to encompass the full range of software.

Explanation

Akbar constructed the Attock fort.

The QuizMaster of AnsweringExams.Com suggests remembering this fact by associating it with the year 1581, when Akbar ordered the construction of the fort, and the number 4, since Attock is the 4th most important fort built by Akbar in the region. Other options are incorrect because they do not align with historical records of the Mughal Empire’s expansion and fortification efforts during Akbar’s reign.

Explanation

China and Britain fought the First China War, also known as the Opium War. This answer is correct because the conflict was sparked by China’s attempt to restrict British trade in opium, leading to a series of military engagements between the two nations from 1839 to 1842. The QuizMaster of AnsweringExams.Com recommends associating the year 1839 with the number 39 on a calendar to remember that the war started in this year, making it easier to recall the correct answer. Other options are incorrect because they involve countries that were not directly involved in the conflict, such as France, Egypt, or Greece, which did not play a significant role in the war.
