Write this story using one of the participles from the brackets to make the story complete,
Have you heard of the Loch Ness Monster? Many people believe that there is a huge animal (living / lived) in Loch Ness in Scotland. The animal is about 50 meters long (including / included) its tail. Nobody knows anything about its (eating / eaten )habits. There are some photos of the animal (taking/ taken ) by different people (visiting / visited) the lake, but nobody can prove that they are real. This animal (giving / given) the nickname Nessie has been one of the greatest tourist attractions to the area for years. Expeditions (sending/ sent) to Scotland tried very hard to find and catch Nessie. And so did individuals ( looking/ looked) for the animal. Nessie ( seeing/ seen) now and again is still a great mystery. Very few things ( knowing / known) about Nessie are: it has a long and thin neck like a giraffe s its head is quite small and looks like a horse s or a snake s head its colour is dark yellow and its habitat is the deepest and the coldest part of the lake.
