Rationale: The correct answer is A, the tofu-mushroom-spinach lasagna. Mirella is an ovo-lacto vegetarian, meaning she eats eggs and dairy but avoids animal flesh. This dish meets her dietary requirements as it is a vegetarian option that contains tofu and cheese for protein.

Choice B, the veggie burger, may contain wheat in the bun, which is not suitable for Mirella. Choice C, salmon with cream sauce, contains animal flesh and is not vegetarian. Choice D, stuffed baked potato with vegetable soup, may include wheat products in the soup, making it unsuitable for Mirella's wheat allergy.

In this context, Ermengarde finds her great-aunt's views on dating and relationships to be old-fashioned or out of touch with modern ideas.

Choice C is incorrect as the passage mentions her suffering from seizures due to a head injury, not as a primary reason for describing her life as a slave. Choice D is incorrect as the passage briefly mentions her experience as a nursemaid for a baby, but it does not focus on her love for babies as a key aspect of describing her life as a slave.

Choice A is incorrect as it falls on Monday, and she gets off work at 5:30 PM. Choices B and D are also incorrect as she needs time to settle in after work before going online to register.
