SECTION 1: GENERAL SCIENCE Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A combat medic is treating a soldier exhibiting signs of heat stroke after a 10-mile road
march in 105-degree heat. The soldier's core temperature is elevated and he has ceased
sweating. The medic immediately begins evaporative cooling and IV fluid resuscitation. What
physiological failure is the medic primarily attempting to correct?
A. The breakdown of the body's thermoregulatory mechanisms that normally dissipate heat ✓
CORRECT
B. The depletion of glycogen stores in the liver and muscles
C. The accumulation of lactic acid in the bloodstream from overexertion
D. The constriction of peripheral blood vessels preventing heat loss
Correct Answer: A
Rationale: Heat stroke is defined by the failure of the body's thermoregulatory mechanisms,
particularly the inability to dissipate heat through sweating and vasodilation, leading to
dangerous core temperature elevation. The medic's cooling interventions target this specific
breakdown to prevent organ damage and neurological injury. On the ASVAB, distinguish heat
stroke from heat exhaustion by remembering that heat stroke involves hot, dry skin and
altered mental status due to failed thermoregulation.
Question 2 of 50
A military fuel specialist is analyzing a sample of JP-8 jet fuel to determine its combustion
efficiency. The specialist notes that the fuel contains hydrocarbon chains of varying lengths.
Which property of hydrocarbons most directly determines how completely the fuel will burn in
a jet engine?
A. The viscosity of the fuel at room temperature
B. The ratio of carbon to hydrogen atoms in the molecular structure ✓ CORRECT
,C. The color and opacity of the liquid sample
D. The fuel's resistance to electrical conductivity
Correct Answer: B
Rationale: The combustion efficiency of hydrocarbon fuels depends on the
carbon-to-hydrogen ratio, with higher hydrogen content enabling more complete combustion
and cleaner exhaust products. A balanced ratio ensures sufficient oxygen availability during
the combustion reaction to minimize carbon monoxide and soot formation. When analyzing
fuel properties on the ASVAB, focus on molecular composition rather than physical
characteristics like color or viscosity.
Question 3 of 50
An artillery crew is calculating the trajectory of a shell fired at a 45-degree angle. The crew
chief knows that air resistance is negligible and wants to maximize the horizontal distance
traveled. Which factor primarily determines the maximum range of the projectile in this
scenario?
A. The mass of the artillery shell
B. The spin imparted to the shell by the barrel rifling
C. The initial velocity of the shell as it leaves the muzzle ✓ CORRECT
D. The diameter of the shell's explosive payload
Correct Answer: C
Rationale: In projectile motion without air resistance, the maximum horizontal range is
determined by the square of the initial velocity divided by gravitational acceleration, making
muzzle velocity the dominant factor when launch angle is fixed. While launch angle affects
trajectory shape, the range is directly proportional to the square of the initial speed. On the
ASVAB, remember that projectile range depends on both velocity and angle, but velocity is the
primary variable when angle is already optimized at 45 degrees.
Question 4 of 50
A Navy meteorologist is briefing a carrier strike group commander about an approaching
weather system in the Pacific. The meteorologist observes that a warm air mass is moving
into a region currently occupied by cold air. What type of weather front is developing, and
what conditions should the strike group expect?
A. A stationary front producing clear skies and calm winds
B. A cold front bringing rapid temperature drops and high pressure
C. An occluded front with dry conditions and reduced visibility
D. A warm front generating prolonged precipitation and gradual warming ✓ CORRECT
Correct Answer: D
, Rationale: A warm front forms when warm air advances over cold air, creating gradual lifting
that produces prolonged precipitation, overcast skies, and steady temperature rises. This
contrasts with cold fronts, which bring rapid weather changes and short-duration severe
storms. Military meteorology questions on the ASVAB often test your ability to distinguish
frontal systems by their weather patterns and temperature trends.
Question 5 of 50
A preventive medicine specialist is testing water from a forward operating base well and
identifies a microscopic, single-celled organism with flagella. Several soldiers have already
reported severe diarrhea and cramping. Which organism is most likely responsible for this
outbreak?
A. Giardia lamblia, a protozoan that infects the small intestine and causes diarrhea through
contaminated water ✓ CORRECT
B. Staphylococcus aureus, a bacterium associated with skin infections and food poisoning
C. Rhinovirus, the primary cause of the common cold and not waterborne
D. Plasmodium falciparum, a protozoan transmitted by mosquitoes rather than water
Correct Answer: A
Rationale: Giardia lamblia is a protozoan parasite commonly found in contaminated water
sources that causes giardiasis, characterized by diarrhea, cramping, and dehydration. It
spreads through the fecal-oral route via untreated water, making it a significant concern for
field operations. Remember that protozoans are single-celled eukaryotes, unlike bacteria or
viruses, and Giardia is the classic waterborne pathogen tested on military exams.
Question 6 of 50
A munitions specialist is preparing a smoke grenade for a training exercise. The filler
material must transition directly from solid to gas when ignited to produce a dense white
screen. Which chemical property is being exploited in this design?
A. Sublimation, where a substance passes from solid to gas without becoming liquid ✓
CORRECT
B. Combustion, where rapid oxidation produces heat and light
C. Fermentation, where organic compounds break down anaerobically
D. Condensation, where gas turns into liquid
Correct Answer: A
Rationale: Sublimation is the phase transition from solid directly to gas without passing
through a liquid state, making it ideal for smoke grenades that must produce dense vapor
instantly upon activation. Ammonium chloride is a common sublimating compound used in
military smoke munitions for screening and signaling. On the ASVAB, distinguish sublimation
from evaporation and condensation by remembering the direct solid-to-gas pathway.
