[Answer] Which animal is the only marsupial native to the United States?

Step 1 : Introduction to the question "Which animal is the only marsupial native to the United States?"

...The Virginia opossum is the only marsupial (pouched mammal) native to the United States. Marsupials differ from placental mammals in that they give birth to very underdeveloped young, which continue developing in a pouch. While marsupials are most commonly associated with Australia, the opossum is widespread across much of the U.S., especially east of the Rocky Mountains. It is well known for its defensive behavior of “playing dead,” and it plays an important ecological role by consuming insects, rodents, and large numbers of ticks.

[Answer] Which city does not have stop signs?

Step 1 : Introduction to the question "Which city does not have stop signs?"

...Parisians aren’t renowned for their considerate driving, but it might just be because they don’t have the necessary street signage. Paris is the only major capital in the Western world that doesn’t have a single stop sign. In Paris, cars don’t come to a full stop at any intersection without a traffic light. Cars on the right have the right of way, at both intersections and in traffic circles. Paris hasn’t always been a stop-sign-free metropolis though. The city did have one stop sign at one point, situated in Paris’s 16th district. Despite this sign’s unique claim to fame, it disappeared six years ago and has never returned.
