3. Read the following scenario to answer the question below.
A prison gives a code to each inmate according to the following guidelines:
First Digit- Gender
1-Male
2-Female
Second and Third Digit- Age
Two digits represent the inmate's age.
Note: This prison does not have any inmates under the age of 18 or older the age of 85.
Fourth Digit- Length of Sentence
1: 0 – 2 years
2: 2 – 6 years
3: 6 – 12 years
4: 12 – 20 years
5: 20 years – life
The ranges above do not include top values. For example, if someone was given a 6 year sentence, they would be coded with the number 3.
Fifth Digit- Number of prior imprisonments
Note: This prison does not have any inmates who have more than 6 prior imprisonments.
Keep in mind that this number does not include the current imprisonment. Thus, someone who is being imprisoned for the first time will be coded with ‘0’.
The codes are recorded in the same order as they appear above.
Amy is 36 years old and is serving a 12 year sentence. This is her third time being imprisoned. What is her code?
A. 23642
B. 23122
C. 23643
D. 36243
Answer
Click to see the full solution to the question.
ANSWER
| Gender | 2 | Female |
| Age | 36 | 36 |
| Length of sentence | 4 | 12<12<19.9 |
| Number of prior imprisonments | 2 | 2 |
The correct code is 23642.
The second and third digits represent age. Since Amy is 36, the third digit must be 6, eliminating incorrect options.
The last digit represents the number of prior imprisonments. Since she has 2, the final digit must be 2.
Therefore, the correct answer is 23642.

Reading Comprehension - EEI POSS Test Question
5. Read the following passage to answer the question below
Electricity and Benjamin Franklin
The first documentation regarding electricity is dated approximately 600 BC. Thales of Miletus described how an amber stone becomes charged with static electricity by simply rubbing it with a cloth. William Gilbert coined the term electricity which derives from the Greek word elektron (meaning: amber).
In 1663, Otto Von Guericke invented the first electric generator which produced static electricity. The device was made of a sulfur globe with an iron rod affixed to it. The rod served as an axle, allowing the globe to rotate. The globe was safely secured on a wooden base and a handle was used to spin it manually. While spinning, the globe was rubbed with a lining fabric which led to a accumulation of static electricity on the surface of the globe. Various phenomena, such as attraction, repulsion, leaping sparks and crackling sounds, were observed during the charging process, all of which we now attribute to static electricity, an inexplicable phenomenon in Von Guericke's time. The discovery of the electricity phenomenon and the beginning of the electrical era is widely associated with Benjamin Franklin.
His success in the business world provided him with financial security which allowed him to dedicate his time to scientific research. Franklin discovered the existence of positive charge and negative charge and in 1749 he built the first electric battery. Franklin's most renowned experiment proved that lightning originates from an electrostatic discharge. In order to determine that lightning was electricity, he proposed extending a conductor into a cloud that appeared to have the potential to become a thunderstorm. If electricity existed in the cloud, the conductor could be used to extract it. And so, Franklin flew a kite into the sky. At the edge of the kite, an iron wire was attached in order to absorb the electric charge from the air. The iron wire stretched down along the kite's rope to where an iron key was attached. The kite collected the aerial electricity and when Franklin brought the knuckles of his hand closer to the iron key he felt the electrostatic discharge.
Whilst Franklin was not the first to discover electricity or even conduct the experiment he proposed, his understanding of the subject and the polarity terms he coined laid the foundations for future electrical researchers.
In the kite experiment, which part was designed to absorb the electrical charge?
A. The iron wire
B. The iron key
C. The rope
D. A piece of cloth that was attached to the kite
Answer
Click to see the full solution to the question.
ANSWER
The passage states that an iron wire was attached to absorb electric charge from the air.
Option B is incorrect because the iron key only conducted the electricity to Franklin’s knuckles.
Option C is incorrect because the rope only lifted the kite and was not involved in electricity.
Option D is not mentioned in the text.
Thus, option A is the correct answer.

Graphic Problem Solving - EEI TECH Practice Question
6. Take a look at the following graph to answer the question below.
Which product contains the highest amount of Calcium relative to the Net Weight?
A. Blanco
B. Cisco
C. Magic
D. Salty
Answer
Click to see the full solution to the question.
ANSWER
The correct answer is D.
To determine which product has the highest relative amount of Calcium, compare the ratio of calcium to net weight for each product.
Magic: 4/160 → 2/80 → 1/40
Salty: 6/100 → 3/50
Blanco: 6/150 → 2/50 → 1/25
Salty: 10/200 → 1/20
When two fractions share the same numerator, the fraction with the smaller denominator is larger.
Thus, 1/20 is greater than 1/40 and 1/25.
To compare 3/50 and 1/20, rewrite 1/20 with numerator 3:
1/20 → 3/60.
Now compare 3/50 and 3/60.
Since 50 is smaller than 60, 3/50 is larger.
Therefore, Salty has the highest relative amount of Calcium.
