Statement and Conclusions Solution

Solution

We must determine which of the five possible conclusions can be logically and definitively derived from the two given statements.

Combining the Statements:

The statements are "All Scientists working in America and talented" and "Some Indian scientists are working in America." By combining these, we can conclude that the group of Indian scientists who are working in America must also be talented. This leads to the definite conclusion: Some Indian scientists are talented.

Analysis of Conclusions:

  • (b) Some talented Indian scientists have migrated to America: This is a correct rephrasing of our combined conclusion.
  • (d) Some Indian scientists are talented: This is the direct conclusion derived from the statements.
  • (a), (c), (e): These are incorrect. We cannot conclude that *none* are talented (a), that *all* talented scientists are Indian (c), or anything about scientists in India (e).

Conclusion:

The only conclusions that logically follow are (b) and (d).
