Zorluk: OrtaTransitions: Chronology and Sequence

In 1948, physicists Ralph Alpher and Robert Herman first predicted the existence of cosmic microwave background (CMB) radiation as a relic of the Big Bang. For years, their theoretical calculations remained unverified due to the limitations of observational technology. _______ in 1964, radio astronomers Arno Penzias and Robert Wilson detected this faint hum of radiation while testing a sensitive horn antenna, providing the first empirical proof of the prediction.

Which choice completes the passage with the most logical transition?

  1. A
    Furthermore,
  2. B
    Initially,
  3. Eventually,Cevap
  4. D
    In contrast,

Cevap

Eventually,
The correct choice is 'Eventually,' because it logically indicates that the discovery of cosmic microwave background radiation in 1964 occurred after a long period of time and scientific progress following the 1948 prediction.

Adım Adım Çözüm

1
Analyze the chronological sequence of events in the passage.
The timeline begins in 1948 with a theoretical prediction. This is followed by a period of years in which the calculations remained unverified. The final event occurs in 1964 with the empirical detection of the radiation.
Understanding the timeline is necessary to determine the chronological relationship between the sentences.
2
Identify the relationship indicated by the transition.
The transition needs to connect the long period of unverified theory to the subsequent empirical discovery that occurred years later.
Selecting the correct transition requires matching the logical connection of the events with a transition that signals the passage of time leading to a subsequent event.
3
Evaluate the choices to find the transition that indicates chronological progression over time.
'Eventually' is a chronological transition that signals an event occurring after a long delay or series of events. Other transitions signal addition, opposition, or an initial state, which do not fit the chronological context.
This determines the final correct option by eliminating incorrect relationships.
