• A. By the time I arrived, the party had already begun.
• B. I wish I had studied harder for the exam.
• C. We will have finished the project by Monday.
• D. She had been waiting for hours before he finally showed up.

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

2. Which element is used in jewelry due to its malleability and resistance to tarnish?

• A. Iron
• B. Copper
• C. Gold
• D. Silver

Correct answer: C

Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry

3. Which type of tissue is characterized by tightly packed cells with minimal extracellular matrix and provides structural support and protection?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: B

Rationale: The correct answer is B: Connective tissue. Connective tissue is characterized by tightly packed cells with minimal extracellular matrix, which provides structural support and protection. Epithelial tissue, while also tightly packed, is specialized for lining and covering surfaces. Muscle tissue is composed of cells with contractile properties for movement, and nervous tissue is made up of neurons for transmitting electrical signals. Therefore, connective tissue best fits the description of being densely packed with cells and serving a structural support and protective function.

4. Which property of a wave determines its pitch in sound waves?

• A. Amplitude
• B. Frequency
• C. Wavelength
• D. Speed

Correct answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency refers to the number of cycles of a wave that occur in a unit of time, usually measured in hertz (Hz). Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the height of a wave and is related to the loudness of the sound. Wavelength is the distance between two consecutive points in a wave that are in phase, and speed is the rate at which a wave travels through a medium.

5. The muscular sac that stores urine until it is released from the body is called the:

• A. Urethra
• B. Bladder
• C. Ureter
• D. Nephron

Correct answer: B

Rationale: The correct answer is B: Bladder. The bladder is a muscular sac that stores urine until it is ready to be released from the body through the urethra. The urethra is the tube that carries urine from the bladder out of the body. Ureters are tubes that carry urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering the blood and producing urine. Therefore, the bladder is the specific organ responsible for storing urine until it is expelled from the body, making it the correct answer.

6. What is the role of DNA in heredity?

• A. Provides energy for the cell
• B. Determines the structure and function of proteins
• C. Stores and transmits genetic information
• D. Controls cell division

Correct answer: C

Rationale: Rationale: DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms. It stores genetic information in the form of a code made up of four chemical bases: adenine (A), thymine (T), cytosine (C), and guanine (G). This genetic information is passed down from parents to offspring and is responsible for determining an organism's traits and characteristics. DNA does not provide energy for the cell (option A), determine the structure and function of proteins (option B), or control cell division (option D).
