The correct answer is: A. had become
The potato had become the staple food in Ireland by the first half of the 19th century. This is because the potato was a very efficient crop to grow in Ireland. It could be grown in poor soil and with little rainfall. It was also a very filling food, which was important for the poor people of Ireland.
In 1854, a disease called potato blight struck Ireland. This disease caused the potatoes to rot, which meant that there was no food for the people to eat. This resulted in widespread starvation and death.
The other options are incorrect because they do not accurately describe the situation. Option B, “struck,” is incorrect because the potato blight did not strike Ireland until 1854. Option C, “was becoming,” is incorrect because the potato had already become the staple food in Ireland by the first half of the 19th century. Option D, “has struck,” is incorrect because the potato blight struck Ireland in 1854, not in the present day. Option E, “has become,” is incorrect because the potato had already become the staple food in Ireland by the first half of the 19th century, not in the present day.
