The writer wants to organize the sentences below to logically present the chronological steps of Jocelyn Bell Burnell's discovery of the first pulsar. Arrange the sentences in the most logical order to achieve this goal.
- 1In the summer of , postgraduate student Jocelyn Bell Burnell began analyzing hundreds of meters of paper chart data generated by a new radio telescope.
- 2While scanning the charts, she noticed a strange, recurring "scruff" of radio interference that did not look like typical cosmic noise.
- 3Closer inspection revealed that this anomaly was a series of highly regular pulses occurring every seconds.
- 4Although she and her advisor initially joked that the signal might be a beacon from an alien civilization, they soon realized they had discovered a rapidly spinning neutron star—a pulsar.
Cevap
The correct sequence begins with the introduction of Jocelyn Bell Burnell analyzing chart data, followed by her noticing the anomalous scruff, then the inspection revealing regular pulses, and concluding with the realization that the signal was a pulsar.
The correct order follows a clear chronological progression. First, the context of scanning charts is set. Second, the scanning leads to noticing a strange 'scruff.' Third, closer inspection of this 'scruff' (referred to as 'this anomaly') reveals regular pulses. Fourth, these pulses (referred to as 'the signal') are identified as a pulsar, concluding the narrative.
