She needed to _________ after getting into a car accident that left her with many injuries.rehabilitateadornexertgrieve

To determine the correct word to fill in the blank, let's analyze the context of the sentence.

The sentence states that she got into a car accident and was left with many injuries. The word that best fits this context should be related to recovery or dealing with the aftermath of physical trauma.

1. rehabilitate - This means to restore someone to health or normal life through training and therapy after imprisonment, addiction, or illness. This word is highly relevant to recovering from injuries.

2. adorn - This means to decorate or add beauty to something. This does not fit the context of injuries or recovery.

3. exert - This means to apply or bring to bear (a force, influence, or quality). While it can relate to physical activity, it does not directly connect to recovering from injuries in the context of the sentence.

4. grieve - This refers to feeling deep sadness, especially due to loss. While it can relate to emotional recovery after an accident, the injuries imply a need for physical recovery, making this a less fitting choice.

Based on this breakdown, the best word to complete the sentence is rehabilitate.

Final Answer:

She needed to rehabilitate after getting into a car accident that left her with many injuries.
