A.I. Explanation:

Option 1: "By using their paws to grab the insects."

Explanation: This option is incorrect because the text does not mention toads using their paws to catch prey. Instead, it describes the toad's method of using its tongue. The phrase 'using their paws' is not supported by any information in the text.

Option 2: "By camouflaging themselves and waiting for the prey to come close."

Explanation: This option is incorrect as the text does not discuss camouflage as a method for catching prey. The focus is on the toad's active hunting technique, specifically the use of its tongue, rather than waiting for prey to approach.

Option 3: "By flicking out their long, sticky tongue to snap the prey into their mouth."

Explanation: This option is correct because the text explicitly states that toads catch their prey by flicking out their long, sticky tongue and snapping the insect into their mouth. This action is described in detail, highlighting the quick motion involved in capturing prey.

Option 4: "By chasing the prey until it is caught."

Explanation: This option is incorrect because the text does not mention toads chasing their prey. Instead, it describes a method where the toad moves close to the prey and uses its tongue, rather than pursuing it.
