Meaning: To 'oppose' means to act against or resist something.

Wrong options:

• linearly: 'Linearly' is an adverb that describes a relationship or progression, which does not fit as it does not describe an action related to current flow.
• meaningful: 'Meaningful' is an adjective that describes significance, which does not relate to the action of resistance in this context.
• flowing: 'Flowing' is a present participle that describes the action of current but does not fit as a verb describing resistance.
• sufficient: 'Sufficient' is an adjective that means adequate, which does not relate to the action of opposing current.
• defined: 'Defined' is a past participle that does not convey an action related to resistance in this context.
• passes: 'Passes' is a verb that describes the action of current moving through, but it does not convey the opposing action of resistance.

Correct answer: flowing

Explanation: The word 'flowing' is a present participle that describes the action of electric current in this context. It fits grammatically as it complements the noun 'current' and aligns with the definition of resistance as it relates to the current's movement.

Meaning: 'Flowing' refers to the movement of electric current through a conductor.

Wrong options:

• linearly: 'Linearly' is an adverb that describes a relationship or progression, which does not fit as it does not describe the action of current.
• resistance: 'Resistance' is a noun that does not fit grammatically in this context as it does not describe the action of current.
• meaningful: 'Meaningful' is an adjective that describes significance, which does not relate to the action of current in this context.
• defined: 'Defined' is a past participle that does not convey the action of current flowing.
• sufficient: 'Sufficient' is an adjective that means adequate, which does not relate to the action of current.
• passes: 'Passes' is a verb that describes the action of current moving through, but it does not fit grammatically as it does not complement 'current'.

Correct answer: resistance

Explanation: The term 'resistance' is a noun that fits grammatically as it serves as the subject of the sentence. It aligns with the context of discussing the properties of a conductor and its relationship to length and area.

Meaning: 'Resistance' refers to the opposition to the flow of electric current in a conductor.

Wrong options:

• linearly: 'Linearly' is an adverb that describes a relationship or progression, which does not fit as it does not describe a property of the conductor.
• meaningful: 'Meaningful' is an adjective that describes significance, which does not relate to the property of a conductor in this context.
• flowing: 'Flowing' is a present participle that describes the action of current, which does not fit as a subject in this context.
• defined: 'Defined' is a past participle that does not serve as a noun describing a property.
• sufficient: 'Sufficient' is an adjective that means adequate, which does not relate to the property of resistance.
• passes: 'Passes' is a verb that describes the action of current, which does not fit as a subject in this context.

Correct answer: defined

Explanation: The word 'defined' is a past participle that fits grammatically as it describes the state of resistivity. It aligns with the context of explaining what resistivity is in relation to resistance.

Meaning: 'Defined' means to explain the meaning or nature of something.

Wrong options:

• linearly: 'Linearly' is an adverb that describes a relationship or progression, which does not fit as it does not describe the state of resistivity.
• resistance: 'Resistance' is a noun that does not fit grammatically as it does not describe the state of resistivity.
• meaningful: 'Meaningful' is an adjective that describes significance, which does not relate to the definition of resistivity in this context.
• flowing: 'Flowing' is a present participle that describes the action of current, which does not fit as a description of resistivity.
• sufficient: 'Sufficient' is an adjective that means adequate, which does not relate to the definition of resistivity.
• passes: 'Passes' is a verb that describes the action of current, which does not fit as a description of resistivity.

Correct answer: linearly

Explanation: The word 'linearly' is an adverb that fits grammatically as it describes how resistivity increases with temperature. It aligns with the context of discussing the relationship between resistivity and temperature.

Meaning: 'Linearly' refers to a direct proportional relationship, indicating a consistent increase.

Wrong options:

• resistance: 'Resistance' is a noun that does not fit grammatically as it does not describe the manner of increase.
• meaningful: 'Meaningful' is an adjective that describes significance, which does not relate to the manner of increase in resistivity.
• flowing: 'Flowing' is a present participle that describes the action of current, which does not fit as a description of how resistivity increases.
• defined: 'Defined' is a past participle that does not convey the manner of increase in resistivity.
• sufficient: 'Sufficient' is an adjective that means adequate, which does not relate to the manner of increase in resistivity.
• passes: 'Passes' is a verb that describes the action of current, which does not fit as a description of how resistivity increases.
