Zorluk: OrtaTransitions: Chronology and Sequence

In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a treatment for malaria, when his experiment went awry and produced a dark, sticky sludge. As he was cleaning his flask with alcohol, however, he noticed that the substance left a brilliant purple residue on the glass. _______ he patented this new substance as 'mauveine'—the world's first synthetic dye—and launched the modern chemical industry.

Which choice completes the passage with the most logical transition?

  3. C

  4. D
    For instance,

Cevap

The transition 'Subsequently' is the correct choice because it logically connects the chronological steps of Perkin noticing the residue and then patenting it.
The passage describes a sequence of events: first, Perkin noticed a purple residue while cleaning his flask; next, he patented the substance and launched an industry. The transition 'Subsequently' is correct because it logically signals a subsequent step in a chronological sequence.

Adım Adım Çözüm

1
Analyze the relationship between the sentences before and after the blank.
The sentence before the blank describes Perkin noticing a purple residue. The sentence with the blank describes him patenting the substance and starting an industry.
Understanding the connection between these events determines the appropriate category of transition word.
2
Identify the chronological order of the actions.
Noticing the residue happened first. Patenting the substance occurred after this discovery.
A sequential or chronological transition is needed to show that the second event followed the first.
3
Evaluate the choices to find the one that establishes a subsequent chronological relationship.
'Subsequently' correctly indicates that the patenting occurred after the discovery. Other options represent incorrect relationships like reverse chronology, contrast, or exemplification.
Selecting the correct transition ensures the text flows logically and accurately represents the historical timeline.
