She was appointed . . . . . . . . head of department this term.
Answer:
A unique role within a specific organization is definite by context. 'The head of department' identifies a singular office. Using 'a' would imply one among several equivalent posts. Hence, 'the' is appropriate.
83872
He cooked . . . . . . . . delicious meal for his guests last night.
Answer:
a
The noun 'meal' is singular and countable, first mentioned here, so 'a' is required. The adjective 'delicious' does not change article choice. 'The' would presuppose prior identification of this specific meal. Therefore, 'a delicious meal' is correct.
83873
They visited . . . . . . . . Ganges during their trip to India.
Answer:
Rivers take the definite article, e.g., 'the Ganges'. The referent is unique and specific. Omitting the article would be ungrammatical. Thus, 'the Ganges' is standard.
83874
He’s reading . . . . . . . . encyclopedia entry on Roman law.
Answer:
The noun 'encyclopedia' starts with a vowel sound, so 'an' is correct. The entry is introduced for the first time, justifying an indefinite article. 'A' would be phonetically incorrect. 'The' would suggest a specific, previously mentioned entry.
83875
She poured . . . . . . . . water into the beaker until it reached 100 ml.
Answer:
When referring to an uncountable substance generically, no article is used. The sentence does not specify a particular water previously identified. 'The water' would indicate a specific sample. Therefore, no article suits the generic substance reading.
83876
He looked at . . . . . . . . sky and saw dark clouds gathering.
Answer:
The sky is treated as a unique, contextually shared referent, taking the definite article. Speakers understand 'the sky' as the singular expanse overhead. Indefinite articles are not idiomatic here. Hence, 'the sky' is correct.
83877
She has . . . . . . . . NGO background in health policy.
Answer:
The initialism 'NGO' begins with 'en', a vowel sound, so 'an' is appropriate. Article choice depends on pronunciation, not orthography. 'A NGO' would be phonetically incorrect. The reference is non-specific and first mention.
83878
We discussed . . . . . . . . ethics of artificial intelligence in class.
Answer:
The 'of'-phrase defines a specific subfield ('ethics of artificial intelligence'), which licenses the definite article. The phrase points to a particular domain rather than ethics in general. 'No article' would make the reference overly generic. Therefore, 'the ethics of…' is correct.
83879
They traveled by . . . . . . . . bus to the conference venue.
Answer:
The preposition 'by' with modes of transport normally omits the article ('by bus', 'by car', 'by train'). This expresses the means abstractly. Adding an article would change the meaning or sound awkward. Thus, no article is correct.
83880
He took . . . . . . . . bus because it was raining heavily.
Answer:
Public transport in a habitual or contextually specific sense often takes 'the' ('take the bus', 'catch the train'). The definite article refers to the usual service relevant in context. Using 'a' would imply any single bus, which is less idiomatic. Therefore, 'the bus' is preferred.
