Final answer:
It is true that William of Orange was in line for the throne of England through his marriage to James II's daughter, Mary. However, the generalization that many women could not handle the burdens of war is false, as women's wartime experiences have been diverse and crucial.
Step-by-step explanation:
The question concerns whether it is true or false that William of Orange, who was married to James II's daughter, Mary, was also in line for the throne of England. The content loaded Luna has twin daughters with her husband seems to be an unrelated statement and is not pertinent to the historical question at hand. To provide an answer: It is true that William of Orange, being married to Mary the daughter of James II was in line for the throne of England.
This historical fact is associated with the events leading up to the Glorious Revolution of 1688. As for the statement regarding many women finding themselves incapable of handling the burdens of war when their husbands and fathers went off to fight this is overly generalized and does not reflect the varied experiences of women during wartime throughout history. Therefore this statement can be considered false, as women have played critical roles at home and even in combat throughout various conflicts.
