A sentence is provided in indirect speech. From the four given options, choose the one that most accurately conveys the sentence in its corresponding direct speech. The geologist explained that tectonic shifts were inevitable.

Correct — B. Going back to direct speech, drop that, put the speaker's words in quotation marks and use a plain reporting verb: said the geologist.

The key keeps the reported clause word for word, Tectonic shifts were inevitable. It reads were as the geologist's own tense, since reported speech may leave a past simple unchanged.

Nothing in the content is altered: option (b).

Why the others are wrong

• (a)
  The geologist said, "Tectonic shifts are inevitable." — Are changes the tense the key keeps. The key reads were as the geologist's own past tense, so the direct form repeats were rather than turning it into a present-tense claim.
• (c)
  The geologist explained, "Tectonic shifts will occur." — Will occur is a forecast, not the claim. Inevitable says the shifts cannot be avoided; this option drops that word and changes the tense.
• (d)
  "Inevitably, tectonic shifts occur," he said. — Inevitably, tectonic shifts occur turns the adjective into an adverb and the tense into present, and he replaces the geologist the sentence names.

Indirect to direct speech reverses the usual changes: remove that, restore the speaker's own pronouns and tense, and add quotation marks.

The tense step is where this item turns. After a past reporting verb such as explained, a present tense is normally shifted back: are → were, is → was, will → would. So reported were usually stands for a spoken are.

A past simple in the original may stay as it is when reported, so were can also stand for a spoken were. The key takes that second reading.

Key facts

• Indirect to direct: drop that, restore the speaker's pronouns and tense, add quotation marks.
• After a past reporting verb, present tenses shift back: are → were, is → was, will → would.
• A reported past simple may be left unchanged, so it can come from a spoken past simple.

Common traps

• Treating the verb in the that-clause as the speaker's exact words when a past reporting verb may have shifted it.
• Choosing a paraphrase such as will occur or inevitably occur, which changes what the speaker claimed.
