The passage explores the phenomenon of codes within linguistic and visual systems. It argues that while many codes might appear inherent or 'naturally' given within a culture, this perception is actually the result of certain codes becoming deeply integrated or 'naturalized'. This naturalization is so profound that it makes the underlying practices of coding seem invisible, causing people to perceive them as universal truth. However, this perception obscures the cultural and ideological processes involved in coding. The key point is the difference between codes that are truly natural and those that have been made to appear so through widespread use and early learning, thus concealing the coding mechanisms.
| Option | Explanation |
|---|---|
| 1 | This option incorrectly suggests all codes have a natural origin, whereas the passage talks about some codes being perceived as natural due to their extensive use. |
| 2 | Focuses on ideology and some codes being naturalized, but the passage's emphasis is on the deep integration of codes making them seem natural. |
| 3 | Highlights learning at an early age; however, it misconstrues the passage's main point about the universal appearance of certain codes. |
| 4 | Correct. Accurately captures how some codes are so widespread that they appear natural and obscure the coding process. |
Thus, Option 4 is the most accurate summary as it encapsulates the essence of how both linguistic and visual signs, when widely accepted, seem naturally given while concealing their constructed nature.
The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
In investigating memory-beliefs, there are certain points which must be borne in mind. In the first place, everything constituting a memory-belief is happening now, not in that past time to which the belief is said to refer. It is not logically necessary to the existence of a memory-belief that the event remembered should have occurred, or even that the past should have existed at all. There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago. Hence the occurrences which are CALLED knowledge of the past are logically independent of the past; they are wholly analysable into present contents, which might, theoretically, be just what they are even if no past had existed.
For any natural number $k$, let $a_k = 3^k$. The smallest natural number $m$ for which \[ (a_1)^1 \times (a_2)^2 \times \dots \times (a_{20})^{20} \;<\; a_{21} \times a_{22} \times \dots \times a_{20+m} \] is:
