Please help me!!!
1. A box contains two types of colored pencils: red and blue. It also has a few pens. You can pick only one item at a time. If you pick either a red or a blue-colored pencil, you get one point. If you pick the pen, you get zero. If you pick a red and a blue pencil at the same time, you get zero again. Which logic gate idea are we using in our game?
A. NAND
B. XOR
C. XNOR
D. NOR

2. Type the correct answer in the box. Spell all words correctly.
What is the output of 1101 x 10 == 11000 + 10?
The output of 1101 x 10 == 11000 + 10 is _ .

3. Bob is searching for a website using the two words theory and practice. After several searches, he finds only one website that has both the words. Most of the other results have only one of the two words. Some results don’t have either of the two words. Which logic gate principle will help Bob find the most appropriate result?

The logic gate principle will help Bob find the most appropriate result.

Logic gates are practical implementation of a digital circuit. There are three basic logic gates, namely; AND, OR and NOT gates. Every other gates are derived from them.

XOR, also called exclusive OR is derived from the OR gate. It gives a high output ( ON or '1') when the inputs are odd (that is, it gives one value or ON state when one of a two-input gate is ON or high). The output for an even 'zero' or 'one' input, is a zero or off or low state.

To represent XOR for two inputs: A⊕ B⇒Y(output).
