Zorluk: ZorDetermining Stated Sequence of Events

Dr. Helen Vance published her seminal paper on cosmic microwave anomalies in the winter of 1948, validating a theoretical model she had constructed six years prior during her residency at the Cambridge Observatory. However, the path to this discovery was non-linear. Before arriving in Cambridge, Vance worked as a technician at a meteorological station in Aberystwyth, where she first observed unexplained signal distortions. It was not until 1944—two years after her arrival at Cambridge and immediately before her team secured high-altitude telemetry data—that she re-evaluated those early Aberystwyth logs. That re-evaluation prompted her to redesign the observatory's primary spectrograph, a task completed just months prior to her 1948 publication.

Based on the passage, which of the following events occurred chronologically AFTER Dr. Vance constructed her theoretical model at Cambridge, but BEFORE her team secured high-altitude telemetry data?

  1. She re-evaluated the signal logs she had compiled in Aberystwyth.Cevap
  2. B
    She observed unexplained signal distortions while working at a meteorological station.
  3. C
    She completed the redesign of the observatory's primary spectrograph.
  4. D
    She published her landmark paper on cosmic microwave anomalies.

Cevap

Dr. Vance re-evaluated her Aberystwyth signal logs in 1944, which falls after her 1942 model construction and immediately before her team secured telemetry data.
The passage establishes that Dr. Vance constructed her theoretical model six years prior to 1948 (in 1942). Her re-evaluation of the Aberystwyth logs took place in 1944 (two years after her 1942 Cambridge arrival) and immediately before her team secured high-altitude telemetry data. Therefore, re-evaluating the logs is the only event that occurred after model construction and before telemetry collection.

Adım Adım Çözüm

1
Establish absolute dates from relative statements in the passage
Publication = 1948; Model construction = 1942 (6 years prior to 1948); Cambridge arrival = 1942; Log re-evaluation = 1944 (2 years after 1942 arrival).
Converting relative temporal clues into a chronological timeline allows accurate sequencing.
2
Map remaining events relative to the 1944 log re-evaluation
Aberystwyth signal observation occurred prior to 1942; Telemetry data was secured immediately after the 1944 log re-evaluation; Spectrograph redesign occurred after log re-evaluation, months before 1948.
Tracking explicitly stated order relationships identifies what fell between 1942 and telemetry retrieval.
3
Select the event bounded by model construction (1942) and telemetry data retrieval (post-1944 re-evaluation)
Re-evaluating the Aberystwyth logs took place in 1944, satisfying both chronological boundaries.
1944 occurs after 1942 and immediately prior to securing the telemetry data.
