Fill in the blanks with the correct articles: a) sun rises in the east. b) She is honest girl.

a) The sun rises in the east. b) She is an honest girl.

Explanation:

a) The definite article "the" is used before "sun" because it refers to a specific celestial body (the sun in general, known to both speaker and listener). In English, we use "the" when referring to unique or well-known entities (e.g., the moon, the Earth).

b) The indefinite article "an" is used before "honest" because:

• "Honest" begins with a vowel sound (/ɒn-ist/), so "an" is correct (not "a").
• The noun "girl" is singular and unspecific (not a particular girl), so an indefinite article is needed.

Note: If the sentence in (b) referred to a specific girl (e.g., "She is the honest girl in class"), "the" would be used. Here, it is general, so "an" fits.
