Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
It is only possible to know the details and example that the author used, with the reading of the text. However, according to the knowledge we have about Cleopatra, we can infer that the author may have shown that because she was a woman, Cleopatra's leadership was often questioned and devalued and therefore, she needed support from men for the policies created by her were efficiently established. However, while these men helped her, they also wanted to take her power, making them unreliable.
