Question

multiple choice 1 pt mark the correct answer. 11. what is the primary focus of astronomy? study of human behavior study of celestial objects and phenomena study of earth’s atmosphere study of chemical reactions

Explanation:

• "Study of human behavior" is related to psychology (Social Science), not astronomy.
• Astronomy is the scientific study of celestial objects (like stars, planets, galaxies) and phenomena (like black holes, supernovae) in the universe. So "Study of celestial objects and phenomena" matches.
• "Study of Earth’s atmosphere" is meteorology (Natural Science, a subfield related to Earth's atmosphere, not astronomy).
• "Study of chemical reactions" is chemistry (Natural Science), not astronomy.

Answer:

B. Study of celestial objects and phenomena (assuming the option with "Study of celestial objects and phenomena" is labeled as B; adjust the label as per the actual option numbering, but the text is the correct choice)
