question:
[header] How to catch a snake [title] Coax the snake into a net. [step] You can catch a snake using a long slender object like a badminton or tennis racket, or a long broom handle attached to a mosquito net. When you see the snake, you'll want to get quickly to the scene. <sep> (A) Don't approach the snake until it's calm. The longer you get up close to it, the more likely it is that you'll scare it away. (B) Once the snake has stretched out and you are able to grab it, pull it gently toward your body or into a net and secure it with a piece of string. [substeps] Be careful to use the wire if you want to keep a strong grip on the snake and reduce the likelihood of biting the animal. (C) Place your net in front the snake's head and coax the snake into the net. The long slender object you attach to the net should be long enough to keep your body a safe distance from the snake, while attempting to net it. (D) Take the first step before catching the snake so it doesn't get too close. Move towards the snake, and hold the net in front of you.

C

question:
[header] How to remove a knobset lock [title] Examine the base of your knob to determine what kind it is. [step] There are two main types of doorknobs with hidden levers. These hidden levers can be in the form of a thin slot or a pinhole. <sep> (A) [substeps] A button lever is inserted through an anvil shaped slot into a face. A screw lever is inserted through an eye pin on the front of the doorknob. (B) [substeps] If your knob contains a heavy metal panel or latch, then this is usually the base and you can use your fingernail to pry it loose. Note if there are any grips or handles on your knobs. (C) Since they are designed to be sealed, they are usually hidden from the inside of your door and can be constantly tampered with. [substeps] Numerically, just about any knob will work. (D) Determine which kind of knob you have, because each knob will detach from the door differently. [substeps] These hidden levers are also called detents.
