The intertwining crises of food (A)/ and energy security

Solution

In part A-  'The intertwining crises of food' is incorrect because 'intertwining' is not the right adjective to describe crises in this context. The correct word is 'intertwined,' which means closely connected or linked, emphasizing the nature of the crises. Also, in part B- The phrase 'is defining' is incorrect because the subject, 'crises,' is plural. Therefore, the correct verb form should be 'are defining.' The intertwined crises of food and energy security are defining the trajectory of the 21st century, casting a long shadow over global stability.
