Question

The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:
1.Man has used poisons for assassination purposes ever since the dawn of civilization, against individual enemies but also occasionally against armies.
2. These dangers were soon recognized, and resulted in two international declarations—in 1874 in Brussels and in 1899 in The Hague—that prohibited the use of poisoned weapons.
3. The foundation of microbiology by Louis Pasteur and Robert Koch offered new prospects for those interested in biological weapons because it allowed agents to be chosen and designed on a rational basis.
4. Though treaties were all made in good faith, they contained no means of control, and so failed to prevent interested parties from developing and using biological weapons.

• A. 1234
• B. 4321
• C. 3241
• D. 1324

Answer 1

The Correct Option is D

To construct a coherent paragraph from the given sentences, we need to determine the logical flow of ideas. Let's examine each option:

• 1: Man has used poisons for assassination purposes...
• 3: The foundation of microbiology by Louis Pasteur...
• 2: These dangers were soon recognized...
• 4: Though treaties were all made in good faith...

Now, we analyze the order:

• Start with 1: It introduces the historical use of chemical and biological methods in warfare.
• Follow with 3: It expands on the topic by introducing the advancement in microbiology, offering new methods for biological weapons which continue the historical narrative.
• Continue with 2: This sentence indicates the dangers were recognized, leading to international efforts to curb such warfare methods, chronologically following the scientific developments.
• Conclude with 4: It gives a critical perspective on the ineffective enforcement of those international agreements, closing the paragraph.

The correct sequence of sentences is therefore 1324.

Answer 2

Statement (1) provides a broad introduction to the subject: a preference for utilizing poison or related substances, noting its historical significance dating back to the earliest civilizations.
Statement (3) expands on this notion by highlighting how certain advancements provided fresh opportunities for those interested in this field.
Statement (2) elaborates on the measures taken to address the dangers associated with this domain once they were recognized.
Statement (4) specifically identifies a weakness in these protective measures. 
Thus, the sequence (1)-(3)-(2)-(4) constitutes a coherent progression of ideas.

So, the correct option is (D): 1324
