Choose one word for the given words - Something that reminds one of past events
Explanation
Explanation
A 'memento' is exactly defined as an object kept as a reminder of a person or past event, such as a souvenir or keepsake. The other words mean 'unwilling' (reluctant), 'impressive' (spectacular), and 'a safe place/protected area' (sanctuary), none of which fit. So the correct one-word substitute is Memento, option (1).
PRO TIP
Re-check your working by substituting the answer back into the original question.
