When lighted, the energy of the alcohol in a lamp is:
Detailed Explanation
Alcohol contains stored chemical energy. When the alcohol is ignited, a chemical reaction called combustion occurs. During combustion, the chemical energy stored in the alcohol is transformed primarily into thermal energy (heat) and also into light energy.
Therefore, the best answer is that the energy is transformed from chemical energy to heat energy.
This question tests the learner's understanding of the Law of Conservation of Energy. Energy does not simply disappear when a substance burns. Instead, it changes from one form to another.
Why the Other Choices Are Incorrect
- "Transformed from chemical energy" is incomplete because the question asks what happens to the energy when the alcohol is lighted.
- "Lost while heating is done" is incorrect because energy is not destroyed. It is transformed.
- "Completely destroyed" contradicts the Law of Conservation of Energy.
Priority Concept
Remember: Chemical energy can be transformed into heat and light energy during combustion.
Safety Considerations
Alcohol lamps involve an open flame and should be handled only with appropriate laboratory safety precautions. Students should be taught to keep flammable materials away from the flame and follow proper fire-safety procedures.
Clinical and Teaching Pearl
A useful teaching strategy is to connect abstract energy concepts to everyday examples such as burning fuel, cooking food, or using batteries.
Common Mistake
Do not interpret "energy transformation" as "energy loss." In science questions, distinguish between conversion of energy and destruction of energy.
LET Tip
When a question describes burning, combustion, batteries, food, or mechanical movement, identify the initial form of energy and the resulting form of energy.
Chemical Energy → Combustion → Heat + Light Energy
Pre-school children always watch the body language of their teachers. This means ____.
Detailed Explanation
Body language is a form of nonverbal communication. It includes facial expressions, posture, gestures, eye contact, physical movement, and other behaviors that communicate meaning without relying primarily on words.
Young children are particularly attentive to teachers' behavior. A teacher's facial expression, posture, gestures, and movement can reinforce or contradict the verbal message being delivered.
For example, saying "Good job" while displaying an encouraging facial expression and positive body language sends a consistent message.
Why the Other Choices Are Less Appropriate
- Words represent verbal communication rather than body language.
- Tone of voice is a vocal or paralinguistic component of communication, not body movement or gesture.
- Group discussion is a communication method, but it does not specifically explain body language.
Priority Teaching Intervention
Teachers should ensure that their verbal and nonverbal messages are consistent. Young learners can easily notice facial expressions, gestures, posture, and movements.
Safety and Classroom Considerations
Teachers should avoid intimidating gestures, threatening body language, or facial expressions that may unnecessarily frighten young children. Nonverbal communication should support a safe and positive learning environment.
Clinical and Teaching Pearl
Communication is more than words. Effective teachers communicate through what they say, how they say it, and what their body language conveys.
Common Mistake
Do not automatically select "words" simply because verbal communication is important. Look for the specific clue in the question: "body language."
LET Tip
When the stem mentions facial expressions, gestures, posture, eye contact, or body movement, think nonverbal communication.
Body language = Nonverbal Communication
If you were converting the height of your room for better ventilation, what would 1.60 m be equivalent to?
Detailed Explanation
The metric system is based on powers of 10, making conversions relatively straightforward.
The relationship is:
1 meter = 1,000 millimeters
Therefore:
1.60 m × 1,000 = 1,600 mm
Thus, 1.60 meters is equivalent to 1,600 millimeters.
Why the Other Choices Are Incorrect
- 16 cm is much shorter than 1.60 meters.
- 1,600 cm would equal 16 meters, not 1.60 meters.
- 1.6 dm equals only 0.16 meters.
Priority Concept
Remember the basic metric sequence:
Kilometer → Meter → Centimeter → Millimeter
For meters to millimeters, multiply by 1,000.
Safety and Practical Application
Accurate measurement is important in many real-world applications, including construction, classroom demonstrations, laboratory work, and environmental planning.
Teaching Pearl
Encourage learners to use dimensional relationships rather than memorizing isolated conversion answers.
Common Mistake
A common mistake is confusing centimeters and millimeters. Remember: 1 cm = 10 mm.
LET Tip
For metric conversion questions, identify the direction of conversion. Moving from a larger unit to a smaller unit generally requires multiplication.
1 m = 100 cm = 1,000 mm
It refers to the full and fair equivalent of the property taken from its owner by the expropriator, and the gauge for computation is not the taker's gain but the owner's loss. In order for the payment to be "just," it must be real, substantial, full, and ample; made within a reasonable time from the taking of the property.
Detailed Explanation
Just compensation refers to the fair equivalent that the property owner should receive when private property is taken for a public purpose through the exercise of eminent domain.
The important distinction is:
- Eminent domain is the power of the State to take private property for public use upon payment of just compensation.
- Just compensation is the payment made to the property owner for the property taken.
- Public use refers to the public purpose for which property may be taken.
The wording of the question specifically describes the full and fair equivalent of the property taken, which identifies the answer as just compensation.
Why the Other Choices Are Incorrect
- Property is the subject being taken, not the compensation.
- Public use identifies the purpose of the taking.
- Eminent domain refers to the governmental power used to take private property for public use, subject to legal requirements.
Priority Concept
Eminent Domain = Power
Public Use = Purpose
Just Compensation = Payment
Safety and Legal Consideration
Legal questions should be answered based on the exact wording of the applicable law and controlling jurisprudence. Examinees should avoid assuming that similar legal terms have identical meanings.
Common Mistake
The most common mistake is selecting eminent domain because the question discusses property being taken. Look at what the question is actually defining: the payment for the property.
LET Tip
When several legal terms appear related, identify whether the question is asking about a power, purpose, process, right, or payment.
Eminent Domain → Governmental Power
Just Compensation → Fair Equivalent Paid to the Owner
Which of the following fractions is equal to 12/84?
Detailed Explanation
To determine an equivalent fraction, simplify 12/84 by dividing both the numerator and denominator by their greatest common factor.
The greatest common factor of 12 and 84 is 12.
12 ÷ 12 = 1
84 ÷ 12 = 7
Therefore:
12/84 = 1/7
Checking the Other Choices
- 7/42 = 1/6, so it is not equivalent.
- 1/8 is not equal to 12/84.
- 6/42 = 1/7. This is mathematically equivalent to 12/84.
Important Accuracy Note: The item as written actually has two mathematically equivalent choices: 6/42 and 1/7.
Because:
12/84 = 6/42 = 1/7
Therefore, if this question is intended for a single-answer LET practice test, the item should be revised so that only one option is correct.
How to Improve the Question
A better version would be:
"Which of the following is the simplest form of 12/84?"
Then the unique answer would be: 1/7.
Teaching Pearl
Equivalent fractions can have different numerators and denominators while representing the same value.
For example: 1/7 = 2/14 = 6/42 = 12/84.
Common Mistake
Do not assume that the smallest-looking fraction is automatically the only equivalent fraction. Always verify by simplifying or cross-multiplying.
LET Tip
When asked for the simplest form, divide the numerator and denominator by their greatest common factor.
12/84 ÷ 12/12 = 1/7
Equivalent forms include: 1/7, 2/14, 6/42, 12/84.

LET Study Tips
1. Understand Before Memorizing
Instead of memorizing isolated answers, understand the principle behind each question. This makes it easier to answer questions that are worded differently.
2. Watch for Keywords
LET questions often contain clues. Words such as body language, equivalent, converted, fair payment, primarily, except, and best can help identify what the question is actually asking.
3. Eliminate Clearly Incorrect Choices
If you do not immediately know the answer, eliminate choices that contradict the basic principle being tested.
4. Check Mathematical Questions Carefully
For conversion and fraction questions, do the calculation rather than relying on intuition.
5. Read Every Word in Legal Questions
Legal concepts frequently contain closely related terms. Identify exactly what the question defines before selecting an answer.
Frequently Asked Questions
1. Is this LET reviewer suitable for beginners?
Yes. The questions cover foundational concepts and include explanations that can help beginners understand the underlying principles.
2. Should I memorize the answers?
No. Focus on understanding the concepts. Memorization without understanding becomes less effective when the question is reworded.
3. What subjects should I study for the LET?
Your preparation should cover the relevant areas included in your LET program, including General Education and Professional Education, as well as the appropriate specialization or major content when applicable.
4. How can I improve my LET score?
Combine content review with regular practice tests. After each test, review not only the questions you got wrong but also the questions you answered correctly by guessing.
5. Why is Question 5 problematic?
The question asks which fraction is equal to 12/84, but both 6/42 and 1/7 are mathematically equivalent to 12/84. If used in a single-answer test, the question should therefore be revised.
