I urgently need to revise this paragraph about a program called "Lost".

1) Lost was first transmitted (broadcast) by ABC in 2004. It was soon very popular because of its unusual plot.
2) Lost is the story of the survivors of a plane crash in the Pacific Ocean. The flight took off in Sydney and (the plane /is it necessary??) was flying to Los Angeles, when suddenly the engine stopped and the plane fell out of the sky crashing into the sea.
3) 48 passengers survived the crash and swam to a small island. Luckily, they found part of their plane and cooked and ate food from it. Then they built small houses from trees.
4) While they were living on the island, they went through a lot of frightening experiences.
5) While they were walking in the jungle, for example (?); they saw a huge polar bear.
6) One day they discovered that other people were living on the island but they weren’t friendly at all.

1) Lost was first broadcast [or "aired"] by ABC in 2004. It was soon very popular because of its unusual plot.

2) Lost is the story of the survivors of a plane crash in the Pacific Ocean. The flight took off in Sydney, heading to Los Angeles, when suddenly the engine stopped, and the plane fell out of the sky and crashed into the sea.

3) Forty-eight passengers survived the crash and swam to a small island. Luckily, they found part of their plane and cooked and ate food from it. Then they built small houses from trees.

4) OK

5) While they were walking in the jungle, for example, they saw a huge polar bear. (Did the plane crash north of the Arctic Circle somewhere?)

6) One day, they discovered that other people were living on the island, but those people weren't friendly at all.

To revise this paragraph about the TV show "Lost," we can make a few changes to enhance clarity and flow. Here's the revised version:

"Lost" debuted on ABC in 2004 and quickly garnered a massive following due to its captivating storyline. The show revolves around a group of survivors who find themselves stranded on a small island in the Pacific Ocean following a plane crash. Originally en route from Sydney to Los Angeles, their flight plunges from the sky when the engine abruptly fails.

Out of the initial passenger pool, 48 individuals successfully make it to the island and rely on salvaged plane wreckage for sustenance. These survivors display resourcefulness by preparing and consuming food from the aircraft. Additionally, they adapt their surroundings by constructing shelters using available trees.

Living on the island, the group endures a multitude of terrifying encounters. For instance, while exploring the dense jungle, they unexpectedly encounter a massive polar bear. Added to their list of eerie occurrences, they eventually discover the presence of other inhabitants on the island, although their intentions prove to be far from friendly.

In this revised version, the paragraph structure has been improved to convey the information more effectively. Additionally, unnecessary repetition and redundant questions have been removed for greater clarity.
