The US President has downsized his country’s nuclear arsenal, helped negotiate a deal to halt Iran’s nuclear-weapons programme, and led a global initiative to secure radioactive materials. But his legacy on nuclear issues remains uncertain, as progress in securing nuclear materials has been slow. Which of the following is an assumption of the speaker?

1. There could be a break in the president’s initiative to secure radioactive materials.
2. One’s lasting fame depends on the speed with which one’s initiatives are carried out.
3. The deteriorating progress will eventually lead to the failure of the initiative.
4. The US can never convince a country to give up its nuclear initiatives.

Correct answer: One’s lasting fame depends on the speed with which one’s initiatives are carried out.

Solution

The speaker says the president’s legacy remains uncertain because progress has been slow. This assumes that the speed of implementation affects how lasting or favorable one’s legacy will be. That is exactly what option B states.
