Question 1 of 30
1. Question
Captain Rodriguez is leading a search and rescue mission in a rugged mountain terrain. The team faces challenges navigating through dense forests and steep cliffs while searching for the missing hiker.
What is the primary objective of Captain Rodriguez’s search and rescue mission?Correct
The primary objective of Captain Rodriguez’s search and rescue mission is to locate and rescue the missing hiker. This goal takes precedence over other tasks as it involves saving a life and ensuring the safety of the individual in distress. Mapping the terrain, providing medical aid to wildlife, and surveying for tourist attractions are secondary objectives that may be relevant in certain contexts but are not the primary focus of a search and rescue mission.

Question 2 of 30
2. Question
Which electronic component regulates the flow of current in a circuit and can be used to amplify or switch electronic signals?
Correct
A transistor is a semiconductor device that regulates the flow of current in a circuit and can be used to amplify or switch electronic signals. Transistors have three terminals—emitter, base, and collector—and can function as amplifiers or switches depending on their configuration and the application. Capacitors store electrical charge, resistors limit current flow, and diodes allow current to flow in only one direction, but they do not perform the amplification or switching functions of a transistor. Therefore, the correct answer is the electronic component that regulates current flow and performs amplification or switching functions, known as a transistor.

3. Question
Which of the following words is the antonym of “integrity”?
Correct
Integrity refers to the quality of being honest, upright, and morally sound. An antonym of integrity is a word that represents the opposite meaning, which in this case is “corruption.” Corruption involves dishonest or fraudulent behavior, lack of integrity, and moral decay. The other options—honesty, sincerity, and ethics—are related concepts that align with integrity rather than being its antonym.

6. Question
Which automotive system is responsible for converting mechanical energy generated by the engine into rotational motion to propel the vehicle forward?
Correct
The transmission system in a vehicle is responsible for transmitting power from the engine to the wheels, converting the mechanical energy generated by the engine into rotational motion to propel the vehicle forward or backward. It allows the driver to control the speed and direction of the vehicle by selecting different gears. The suspension system absorbs shocks and vibrations, the exhaust system removes exhaust gases from the engine, and the cooling system regulates engine temperature, but they do not directly contribute to propelling the vehicle forward. Therefore, the correct answer is “transmission system.”

Question 10 of 30
10. Question
A military base has a perimeter of 320 meters. If one side of the base is 80 meters long, what is the length of each of the other three sides?
Correct
To find the length of each of the other three sides of the military base, we need to subtract the length of the known side from the total perimeter and then divide the result by 3. This is because the remaining three sides would each have the same length in a rectangle.
Perimeter of the base = 320 meters
Length of one side = 80 metersTotal length of the other three sides = Perimeter – Length of one side
Total length of the other three sides = 320 meters – 80 meters = 240 metersTo find the length of each of the other three sides, we divide the total length by 3:
Length of each of the other three sides = Total length of the other three sides ÷ 3
Length of each of the other three sides = 240 meters ÷ 3 = 80 metersTherefore, the length of each of the other three sides is 80 meters.

Question 11 of 30
11. Question
Which electronic component stores electrical charge and releases it when needed to smooth out voltage fluctuations in a circuit?
Correct
A capacitor is an electronic component that stores electrical charge. When connected in a circuit, it accumulates charge on its plates, effectively storing electrical energy. When the circuit requires additional energy or when there are fluctuations in voltage, the capacitor releases the stored charge to stabilize the voltage levels or provide additional power. This ability to store and release electrical energy makes capacitors essential components in electronic circuits, especially in power supply and filtering applications.

13. Question
What is the primary function of the respiratory system in the human body?
Correct
The primary function of the respiratory system is to facilitate the exchange of gases between the body and the environment. During inhalation, oxygen is taken into the lungs and diffuses into the bloodstream, where it is transported to cells throughout the body. At the same time, carbon dioxide, a waste product of cellular metabolism, diffuses from the bloodstream into the lungs and is exhaled during exhalation. This process, known as respiration, ensures that cells receive an adequate oxygen supply for cellular respiration while removing carbon dioxide, maintaining proper gas exchange and homeostasis in the body.

Question 21 of 30
21. Question
Which automotive component is responsible for converting the reciprocating motion of the engine’s pistons into rotational motion?
Correct
The crankshaft is responsible for converting the reciprocating motion of the engine’s pistons into rotational motion. As the pistons move up and down within the cylinders during the combustion process, they exert force on the connecting rods, which in turn transmit this force to the crankshaft. The crankshaft then converts this linear motion into rotational motion, which drives the transmission and ultimately powers the vehicle’s wheels. Thus, the crankshaft plays a vital role in the operation of the engine and the propulsion of the vehicle.

What is the term used to describe the process of a solid substance changing directly into a gas without first becoming a liquid?
Correct
Sublimation is the term used to describe the process of a solid substance changing directly into a gas without first becoming a liquid. During sublimation, the solid substance absorbs heat energy from its surroundings, causing its molecules to gain enough energy to break free from the solid phase and enter the gas phase. This process is commonly observed in substances such as dry ice (solid carbon dioxide) and mothballs (solid naphthalene), which undergo sublimation when exposed to certain conditions.
