Hi Elif, let's solve this grammar question together. We need to find the correct conjunction to link two contrasting ideas in this sentence.
Conjunction Choice (YKD-DİL)
First, let's look at the first part of the sentence: the fundamental mechanisms of cellular respiration are now definitively mapped.
1. Definitively mapped: Known, clear, certain.
Now let's look at the second part: the long-term prediction of human cultural development remains a significantly more speculative and inexact science.
2. Speculative and inexact: Uncertain, guessing.
Notice the relationship between these two ideas. One is certain and mapped, while the other is uncertain and inexact. This is a clear contrast.
Let's evaluate our options based on this contrast. Option A, 'As long as', implies a condition, which doesn't fit here.
Option Analysis
A) As long as → Condition (❌)
Option B, 'Because', implies a cause-effect relationship. Knowing one doesn't cause the other to be inexact, so this is wrong.
B) Because → Reason (❌)
