The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.
The dominant hypotheses in modern science believe that language evolved to allow humans to exchange factual information about the physical world. But an alternative view is that language evolved, in modern humans at least, to facilitate social bonding. It increased our ancestors' chances of survival by enabling them to hunt more successfully or to cooperate more extensively. Language meant that things could be explained and that plans and past experiences could be shared efficiently.

Solution
We need to find the two main views about how language evolved. From passage: "The dominant hypotheses in modern science believe that language evolved to allow humans to exchange factual information about the physical world. But an alternative view is that language evolved... to facilitate social bonding."
The passage shows me two competing ideas:
- Dominant view -> language evolved for sharing facts about the world
- Alternative view -> language evolved for social bonding and cooperation
The key insight -> these are two current competing theories, not one replacing the other or evolving over time.
π’ Option 1 -> correct -> captures both views accurately. "Most believe" = dominant hypotheses, "but others think" = alternative view. Shows both factual information theory AND social bonding theory.
π΄ Option 2 -> context-shift -> suggests scholars moved "from" one belief "now" to another. But passage shows these as two current competing views, not a historical shift.
π΄ Option 3 -> scope-error -> talks about "continuously evolving to higher forms" and progression. Passage doesn't discuss continuous evolution or stages - just presents two competing theories.
π Option 4 -> context-shift + degree-error -> says experts are "challenging" one view. Passage doesn't show challenge or conflict, just presents both as existing hypotheses. Also adds judgment words like "narrow" and "merely" not in passage.
The confusion students face -> Options 2 and 4 seem tempting because they mention both theories, but they wrongly suggest one theory is replacing the other, when the passage shows them as competing current views.
