Set 3: Inferences (Intermediate)

Explanation

Answer: B

PASSAGE

Astronomers studying exoplanets—planets orbiting stars other than our sun—have identified thousands of candidates. Most detection methods favor finding large planets close to their stars, leading to a catalog rich in 'hot Jupiters' but potentially underrepresenting Earth-like worlds in habitable zones.

What can be inferred about current exoplanet detection?

A. The catalog accurately represents the distribution of all planet types.
B. Detection biases may skew our understanding of planetary populations.✓ Correct
C. Earth-like planets are confirmed to be extremely rare.
D. All exoplanets discovered are habitable.

Detailed Explanation

Methods 'favor' certain types + 'underrepresenting' others = detection bias distorts our picture.

Key Evidence:

• "favor finding large planets close to their stars"

• "potentially underrepresenting Earth-like worlds"

Why others are wrong: A ('Underrepresenting' means inaccurate distribution.), C (Underrepresentation ≠ actual rarity.), D ('Hot Jupiters' are inhospitable.).
