Answer:
A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
Explanation:
Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
hope i helped :D

Answer:
Arduino
Explanation:
<em>Arduino is a free and open-source electronics platform with simple hardware and software. Arduino boards can read inputs, turn on a sensor and transform it into an output, activate a motor, and turn on an LED. Sara may direct her board by sending a series of instructions to the board's microcontroller. To accomplish so, she used the Arduino programming language and the Arduino Software (IDE), both of which are founded on Processing.</em>
The mechanism transmits rotary motion to reciprocating is the crank and slider. <span>A crank and slider mechanism changes straight-line motion into rotation motion. Typically found in piston engines or piston pumps, this design consists of a rod that connects to a rotating driving beam and a sliding body.</span>
