The task is to summarize the author's position regarding the Japanese government's approach to regulating genetically modified organisms (GMOs). A Japanese government panel suggests only regulating GMOs with foreign genes permanently introduced and not those with edited endogenous genes, except for cultured microbes. The author implies that exempting edited endogenous genes could be risky, despite potential benefits, since unforeseen risks can't be ruled out. Thus, all genetically modified items should undergo consistent safety and labeling checks.
| Key Point | Detail |
|---|---|
| Government Panel Recommendation | Regulate only GMOs with foreign genes. |
| Registration Requirement | Mandatory for modifications, except contained microbes. |
| Editorial Stance | Praises benefits but warns against blanket permission due to risks. |
| Conclusion | Consistent safety checks for all modified products are essential. |
This author's stance aligns with option three: “Exempting from regulations the editing of endogenous genes is not desirable as this procedure might be risk-prone.” This summary reflects caution against unregulated endogenous gene editing, acknowledging potential risks and supporting uniform safety protocols.

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:
