Difficulty: HardVerb Tense, Aspect, and Mood

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.

Step-by-Step Solution

1
Identify the time frame established by the context.
The phrase 'was discovered in Egypt in 1799' establishes a specific event in the past.
Verbs must align with the temporal relationship defined by the text.
2
Determine the relationship between the missing verb and the established past event.
The action of trying to decipher the inscriptions occurred over a period ('for centuries') prior to the discovery in 1799.
Actions that were completed or ongoing prior to a specific point in the past require the past perfect tense.
3
Select the correct past perfect form of the verb 'struggle'.
'had struggled' (past perfect) or 'had been struggling' (past perfect continuous) correctly indicates this sequence.
These forms correctly show that the action occurred before the discovery.
