[Answer] Which mammal often starves to death after losing all its teeth?

Step 1 : Introduction to the question "Which mammal often starves to death after losing all its teeth?"

...African elephants rely on a unique tooth-replacement system in which sets of massive molars grow in from the back of the jaw and move forward as older ones wear down. Over a lifetime, an elephant typically cycles through six sets. Once the final set is worn away—usually in old age—the animal can no longer grind tough vegetation effectively. Because they cannot regrow any additional teeth, many elephants become unable to eat enough food to survive, leading to starvation. This natural limitation is one of the major factors determining an elephant’s lifespan in the wild.

[Answer] Which animal will always give birth to identical quadruplets?

Step 1 : Introduction to the question "Which animal will always give birth to identical quadruplets?"

...Remarkably, the armadillo stands alone in the animal kingdom for producing genetically identical offspring every time it gives birth. The nine-banded armadillo is the only vertebrate that gives birth to identical quadruplets every time! A female releases a single egg that, once fertilized, splits into four embryos—each genetically identical and all sharing one placenta. This phenomenon, in which multiple embryos arise from a single fertilized egg, is known as polyembryony. How and why this rare strategy evolved remains a mystery.

[Answer] Which of these astronauts did NOT walk on the Moon?

Step 1 : Introduction to the question "Which of these astronauts did NOT walk on the Moon?"

...Although Michael Collins was a key member of the historic Apollo 11 crew, he never set foot on the lunar surface. While Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon, Collins remained in lunar orbit aboard the Command Module Columbia, performing critical navigation, communication, and spacecraft maintenance tasks. His role was essential to the mission’s success—without his steady command, Armstrong and Aldrin wouldn’t have had a ride home. Despite never walking on the Moon, Collins is celebrated as one of NASA’s most accomplished and respected astronauts.
