1. Identify the predicate in the following sentence: "The children built a sandcastle on the beach."

• A. on the beach
• B. built a sandcastle
• C. children
• D. the

Correct answer: B

Rationale: The predicate is the verb and any words following it that describe the action or state of being of the subject.

2. What is the CRISPR-Cas9 system used for in gene editing?

• A. To amplify specific DNA sequences.
• B. To cut DNA at specific locations.
• C. To deliver genes into cells.
• D. To sequence entire genomes.

Correct answer: B

Rationale: Rationale: The CRISPR-Cas9 system is a powerful tool used in gene editing to precisely target and cut DNA at specific locations within the genome. This system consists of a guide RNA that directs the Cas9 enzyme to the desired DNA sequence, where it creates a double-strand break. This break can then be repaired by the cell's natural DNA repair mechanisms, allowing for the introduction of specific genetic modifications. Options A, C, and D do not accurately describe the primary function of the CRISPR-Cas9 system in gene editing.

3. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

• A. Her eyes glistened in the moonlight, with tears.
• B. Tears glistened in her eyes with moonlight.
• C. Her eyes, in the moonlight, glistened with tears.
• D. Tears made her eyes glisten in the moonlight.

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

4. Which gland located in the neck is responsible for regulating metabolism, growth, and development?

• A. Parathyroid gland
• B. Thyroid gland
• C. Pituitary gland
• D. Thymus gland

Correct answer: B

Rationale: The correct answer is B: Thyroid gland. The thyroid gland is located in the neck and plays a crucial role in regulating metabolism, growth, and development. It produces hormones such as thyroxine (T4) and triiodothyronine (T3) that control the body's metabolic rate, affecting energy levels and growth. The parathyroid gland (A) regulates calcium levels in the body, the pituitary gland (C) controls several other glands and their hormone production, and the thymus gland (D) is involved in the immune system's development. Therefore, the thyroid gland is the most appropriate choice for the functions described in the question.

5. The tonsils and adenoids are part of the lymphatic system located in the:

• A. Chest cavity
• B. Abdominal cavity
• C. Head and neck region
• D. Pelvic cavity

Correct answer: C

Rationale: The tonsils and adenoids are part of the lymphatic system and are located in the head and neck region. These structures help protect the body from infections by trapping pathogens that enter through the mouth and nose. The tonsils are located at the back of the throat, while the adenoids are located higher in the throat. They play a crucial role in the body's immune response, producing antibodies and helping to fight off bacteria and viruses that are inhaled or ingested. Therefore, the correct answer is C, the head and neck region.

6. Identify the conjunction in the following sentence: He went to the store, but they were already closed.

• A. went
• B. to
• C. but
• D. they

Correct answer: C

Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.
