Option 2: by

Option 3: at

Option 4: up

AfterBoards · Accepted Answer

| Option | Explanation | |---|---| | **Option 1: with** | "With" typically suggests accompaniment or means, as in "presented with evidence," not authorship. It doesn't correctly show who performed the action of presenting, so it doesn't fit here. | | **Option 2: by** | Correct. "Presented by Kahneman, Slovic and Tversky" correctly shows the agent, the people who carried out the action of presenting the evidence. This is the standard passive voice construction: [action] + by + [doer of the action]. | | **Option 3: at** | "At" is used to indicate a specific point, location, or time (e.g., "presented at a conference"), not the doer of an action. It doesn't logically connect to naming the researchers here. | | **Option 4: up** | "Up" doesn't form any meaningful or grammatically correct phrase with "presented" in this context (unlike, say, "given up"). Its usage here would be nonsensical. | Correct answer: by Rule applied: In passive voice constructions, the preposition "by" is used to introduce the doer/agent of the action (e.g., "The report was written by the team," "The evidence was presented by the researchers"). Since the sentence identifies Kahneman, Slovic and Tversky as the people who presented the evidence, "by" is grammatically and contextually correct.
