Question

Arrange the following into a meaningful sequence:
1). Our knowledge about life developed over the centuries thanks to the many philosophers, physicists, chemists and biologists, who examined such complex matters according to their different points of view.
2). Out of this long history, I wish to quote here only one date, the year 1953
3). In that year, Miller and Urey carried out their famous experiment about the primordial universal soup, whose foundations had already been expounded by the Russian chemist Alexandre Oparin in 1924
4). From a mixture of five gases, methane, ammonia, carbon dioxide, hydrogen and water vapor, and an electric discharge as the source of energy, complex molecules were produced, including amino acids.

• A. 1,2,3,4
• B. 1,3,4,2
• C. 2,3,1,4
• D. 3,1,2,4
• E. 1,4,2,3

Answer 1

The Correct Option is A

To solve this question, we need to logically sequence the sentences provided so that they form a coherent narrative related to the advancement of scientific knowledge about life through experiments and discoveries.

1. Analyzing Sentence 1: "Our knowledge about life developed over the centuries thanks to the many philosophers, physicists, chemists and biologists, who examined such complex matters according to their different points of view." This sentence introduces the historical context of scientific development, establishing a foundation for the subsequent narrative.
2. Analyzing Sentence 2: "Out of this long history, I wish to quote here only one date, the year 1953." This sentence picks a specific milestone year from the history of scientific achievements mentioned in Sentence 1.
3. Analyzing Sentence 3: "In that year, Miller and Urey carried out their famous experiment about the primordial universal soup, whose foundations had already been expounded by the Russian chemist Alexandre Oparin in 1924." This sentence provides details about the event that took place in 1953, linking it directly to Sentence 2.
4. Analyzing Sentence 4: "From a mixture of five gases, methane, ammonia, carbon dioxide, hydrogen and water vapor, and an electric discharge as the source of energy, complex molecules were produced, including amino acids." This sentence explains the results of the experiment mentioned in Sentence 3, thereby logically following it.

Based on the analysis, the most coherent sequence of sentences is:

1. Sentence 1: Introduces the historical context of knowledge development.
2. Sentence 2: Highlights the important year 1953 from this history.
3. Sentence 3: Details the specific event taking place in that year (Miller-Urey experiment).
4. Sentence 4: Describes the outcomes of this experiment.

Therefore, the correct order is 1, 2, 3, 4.

The correct answer is: 1, 2, 3, 4.

Answer 2

To arrange the provided statements into a meaningful sequence, we need to follow the logical timeline and flow of information:

1). The passage starts by highlighting how our knowledge about life has evolved over centuries through contributions from various philosophers, physicists, chemists, and biologists. This establishes the context of an ongoing development in understanding life.

2). The next logical step is to specify a significant event within this evolutionary timeline. Hence, we identify the importance of the year 1953. This is where the passage continues after setting the background.

3). In 1953, the breakthrough experiment by Miller and Urey took place, further enhancing our understanding. The passage elaborates on this experiment, indicating it as a pivotal point.

4). The description of the experiment continues by detailing the process and results, such as the production of complex molecules from a mixture of gases using energy sources, which ties back into the historical timeline mentioned earlier.

The sequence that maintains the logical flow and context is:
1,2,3,4
