Final answer:
Janine would most likely need patience to overcome the various challenges of sailing around the world alone, as this journey requires enduring slow progress and option c is correct answer.
Step-by-step explanation:
In the scenario of Janine setting out on her sailboat alone to break the record for the youngest person to sail around the world, the character trait that she would most likely need to overcome obstacles on her journey is patience.
Sailing around the world is a lengthy and challenging endeavor that requires enduring diverse weather conditions, solitude, and unforeseen setbacks. Patience is crucial because Janine would face periods of slow progress, have to wait out storms, and deal with repairs or technical issues that might arise. Moreover, patience helps in managing emotional and psychological challenges, like isolation, which is inevitable in a solo journey.
While traits such as physical strength, cooperation, and resistance to peer pressure could be beneficial, they are less relevant when sailing solo. Patience stands out as the central trait that would enable Janine to maintain calm, stay focused on her goal, and persist despite the obstacles she would encounter.
