Online Tutoring Subject Expertise 5 — Questions and Answers
Question 1: A student asks why figurative language is important in literature. Which answer best reflects a tutor's subject mastery?
- It makes texts longer and more impressive to publishers
- It conveys meaning, emotion, and imagery more efficiently and vividly than literal language alone (Correct answer)
- It is only used in poetry, not prose
- Figurative language is a stylistic decoration with no impact on meaning
Correct answer: It conveys meaning, emotion, and imagery more efficiently and vividly than literal language alone
Figurative language compresses complex ideas and emotions into evocative expressions, enriching both meaning and reader experience.
Question 2: A student is confused about why supply increases when price rises. How should a knowledgeable economics tutor explain this?
- It does not; supply and price are unrelated according to basic economics
- Higher prices make production more profitable, incentivizing suppliers to produce and sell more (Correct answer)
- Suppliers are legally required to increase output when prices rise
- Consumers demand more at higher prices, which forces suppliers to produce more
Correct answer: Higher prices make production more profitable, incentivizing suppliers to produce and sell more
The law of supply holds that higher prices increase the profit incentive, encouraging producers to supply greater quantities.
Question 3: Which approach best demonstrates subject expertise when a student cannot understand a geometry proof?
- Read the proof aloud slowly until the student follows along
- Break the proof into individual logical steps and explain the justification for each (Correct answer)
- Skip proofs and focus on applying formulas instead
- Tell the student that proofs are unimportant for standardized tests
Correct answer: Break the proof into individual logical steps and explain the justification for each
Deconstructing a proof step-by-step and explaining the theorem or postulate that justifies each step builds the student's logical reasoning skills.
Question 4: A student asks whether the mitochondria and chloroplasts originated as independent bacteria. The tutor should explain that this is described by:
- The cell theory, which states all cells come from pre-existing cells
- The endosymbiotic theory, which proposes that these organelles evolved from ancient symbiotic bacteria (Correct answer)
- The germ theory, which explains how microbes cause disease
- The theory of spontaneous generation, now disproven
Correct answer: The endosymbiotic theory, which proposes that these organelles evolved from ancient symbiotic bacteria
Lynn Margulis's endosymbiotic theory explains that mitochondria and chloroplasts are descendants of ancient free-living bacteria that entered into a symbiotic relationship with host cells.
Question 5: A student learning to write argumentative essays asks how a claim differs from a fact. A subject-expert tutor would say:
- Claims and facts are interchangeable terms in academic writing
- A claim is a debatable assertion that requires support; a fact is an objectively verifiable statement (Correct answer)
- Facts are opinions backed by data; claims are unsupported opinions
- Claims are only used in legal writing, not academic essays
Correct answer: A claim is a debatable assertion that requires support; a fact is an objectively verifiable statement
A claim makes a debatable point that the writer must support with evidence, while a fact can be verified independently without argumentation.
Question 6: A student preparing for a physics exam asks what distinguishes speed from velocity. The correct explanation is:
- Speed and velocity are identical concepts measured in different units
- Speed is a scalar quantity (magnitude only); velocity is a vector quantity (magnitude and direction) (Correct answer)
- Velocity is always greater than speed for the same motion
- Speed applies to objects at rest; velocity applies to objects in motion
Correct answer: Speed is a scalar quantity (magnitude only); velocity is a vector quantity (magnitude and direction)
Speed measures how fast an object moves (scalar), while velocity specifies both the speed and the direction of motion (vector).
Question 7: A student who is tutoring for the ACT English section asks why comma splices are errors. A well-prepared tutor should explain that:
- Comma splices are only errors in formal writing, not on tests
- A comma alone cannot join two independent clauses; a coordinating conjunction or semicolon is needed (Correct answer)
- Comma splices are errors because they create sentences that are too long
- The ACT prohibits commas between any two clauses regardless of type
Correct answer: A comma alone cannot join two independent clauses; a coordinating conjunction or semicolon is needed
A comma splice incorrectly uses only a comma to join two independent clauses, which requires either a semicolon, a period, or a comma plus coordinating conjunction.
