Solve for x: 2x² − 5x − 3 = 0
- A. x = 3 or x = −½
- B. x = −3 or x = ½
- C. x = 3 or x = ½
- D. x = −3 or x = −½
Show answer & explanation
Answer: A — x = 3 or x = −½
Factor: (2x + 1)(x − 3) = 0. So 2x + 1 = 0 → x = −½, or x − 3 = 0 → x = 3.
What is the gradient of a line perpendicular to y = 3x − 4?
- A. 3
- B. −3
- C. −⅓
- D. ⅓
Show answer & explanation
Answer: C — −⅓
The gradient of y = 3x − 4 is 3. A perpendicular line has gradient −1/3 (negative reciprocal).
George Orwell's "Politics and the English Language" (1946) argues that political writing has become deliberately vague and dishonest, using euphemisms, abstract nouns, and passive voice to obscure meaning and responsibility.
According to Orwell, what is the primary effect of these language choices?
- A. They make writing more academic and impressive
- B. They obscure meaning and avoid accountability
- C. They allow writers to express complex ideas clearly
- D. They have no real effect on the reader
Show answer & explanation
Answer: B — They obscure meaning and avoid accountability
Orwell explicitly states political writers use vague language to "obscure meaning and responsibility" — hiding who did what and evading accountability.
A sequence is defined by aₙ = 2n + 3. What is the sum of the first 5 terms?
- A. 40
- B. 45
- C. 50
- D. 35
Show answer & explanation
Answer: B — 45
Terms: a₁=5, a₂=7, a₃=9, a₄=11, a₅=13. Sum = 5+7+9+11+13 = 45.
