1. Select the word that makes this sentence grammatically correct. Our subcommittee ___________ on the fourth Wednesday of each month.

• A. meet
• B. meets
• C. meeting
• D. are meeting

Correct answer: B

Rationale: The word 'subcommittee' is singular, so the correct verb to use is 'meets' as it agrees with the singular subject. 'Meets' is the present tense form of the verb that matches a singular subject. Choice A 'meet' is incorrect as it is the plural form of the verb. Choice C 'meeting' is a gerund and does not fit the sentence structure. Choice D 'are meeting' is incorrect as 'are' is not the correct auxiliary verb to pair with 'subcommittee'.

2. What is the primary factor responsible for generating lift on an airplane wing?

• A. Propulsion force generated by the engines
• B. Buoyant forces acting on the entire aircraft
• C. Drag reduction achieved through streamlining
• D. Application of Bernoulli's principle to the airfoil's shape

Correct answer: D

Rationale: The primary factor responsible for generating lift on an airplane wing is the application of Bernoulli's principle. This principle states that the air moving over the curved top surface of the wing has to travel faster, leading to reduced pressure above the wing and creating lift. Engines provide thrust for propulsion, not lift. Buoyant forces are more relevant to lighter-than-air aircraft like balloons or airships, not airplanes. While drag reduction through streamlining is important for efficiency, it is not the primary factor in lift generation. Therefore, the correct answer is D.

3. Which type of change occurs when no change is made to the chemical composition of a substance?

• A. Chemical
• B. Physical
• C. Nuclear
• D. Mechanical

Correct answer: B

Rationale: A physical change refers to alterations in the state of matter without modifying the chemical composition of the substance. Examples of physical changes include changes in state (solid, liquid, gas), shape, size, or phase. In a physical change, the substance may look different or behave differently, but its chemical structure remains the same. On the other hand, chemical changes involve the breaking and forming of chemical bonds, resulting in the creation of entirely new substances with different chemical properties. Nuclear changes involve alterations in the nucleus of an atom, such as radioactive decay. Mechanical changes refer to changes in the position or motion of an object caused by applied forces, like pushing, pulling, or twisting.

4. What does 'defecate' mean?

• A. To retain feces
• B. To expel feces
• C. To eliminate fluid
• D. To excrete mucus

Correct answer: B

Rationale: The correct answer is B: 'To expel feces.' Defecate refers to the act of eliminating solid waste from the body. Choice A, 'To retain feces,' is incorrect as defecation involves getting rid of feces. Choices C and D, 'To eliminate fluid' and 'To excrete mucus,' are also incorrect as they do not accurately define the term 'defecate.'

5. What are the columns of the periodic table called?

• A. Periods
• B. Families
• C. Groups
• D. Rows

Correct answer: C

Rationale: In the periodic table, columns are referred to as groups, not periods, families, or rows. These groups share similar chemical properties due to the arrangement of elements within each group, which is based on the number of valence electrons. The vertical columns help classify elements with similar characteristics. Periods refer to the rows of the periodic table, while families or groups are the vertical columns.
