Choices A and B are mentioned as some of Lamarr's failed inventions in the passage. Choice C refers to the military technology that inspired Lamarr's invention, not her invention itself.

Correct Answer: A

Rationale: The exhaustive description of Eleanor Roosevelt's activities during the war in the Pacific showcases her dedication and compassion towards the troops and wounded.

The other choices are incorrect as there is no mention of her being a military strategist, a commander of troops, or a professional athlete in the provided details.

Correct Answer: B
