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 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
