The passage below is from an academic text about linguistic history. Which form of the verb 'struggle' correctly completes the sentence in accordance with the rules of Standard English conventions?
Answer:Before the basalt slab known as the Rosetta Stone was discovered in Egypt in 1799, European scholars 【had struggled】 for centuries to decipher ancient hieroglyphic inscriptions. Because these researchers had long operated under the false assumption that the characters were entirely symbolic rather than phonetic, they made no progress until the slab provided a bilingual key.
Answer
had struggled (or had been struggling)
The correct answer is 'had struggled' or 'had been struggling'. The sentence describes an action that occurred over a duration ('for centuries') before another event in the past ('was discovered in 1799'). To indicate that an action was ongoing or completed prior to a specific point in the past, the past perfect tense ('had struggled') or past perfect continuous tense ('had been struggling') must be used.
