Sam may not look like most superheroes. After all, he is a dog. He has four legs and fur. However, like all superheroes, Sam has a superpower. His special skill is ___1___ waste, or garbage, to set a good example for visitors. Sam uses his ___2___ to help clean a large park in Chile’s capital city, Santiago. He even wears a green cape — a piece of clothing that many superheroes wear.

Sam’s superpower started with ___3___ in Santiago’s Metropolitan Park with his owner, Gonzalo Chiang. Chiang said he and the dog would find and pick up a lot of garbage ___4___ the way — from plastic bottles to face coverings. Chiang said, “From that, we need to prepare to take away the garbage ___5___ we found on each visit.”

In just one month, Sam and Chiang collected 602 face coverings, 585 bottles and 304 cans. Chiang said, “The walk is ___6___ good chance to clean, rather than litter.” To litter means to throw or leave garbage on the ground in a public place.

Park officials were ___7___ with Sam and Chiang’s effort. ___8___, they decided to use Sam’s image for their campaign urging (敦促) visitors to take better care of the park.

Aravena said the cartoon became much more ___10___ than expected. She added, “It reached different schools and it has been spread very well on social media.”
