Read the sentence below: The old, abandoned house looked **scary** in the dim moonlight. If you used a thesaurus to find a more precise word for **scary**, which synonym would best fit the context of the sentence?

• startling

• eerie

• terrifying

Answer explanation

A thesaurus provides synonyms. While all the options are related to 'scary,' 'eerie' best describes something that is strange, mysterious, and frightening in a way that makes you feel uneasy. This perfectly fits the atmosphere of an old, abandoned house in the moonlight. 'Startling' suggests a sudden shock, 'terrifying' is much more intense, and 'unpleasant' is too general.
