Answer: (c) A-2, B-3, C-4, D-1.
Why each option is right or wrong
- (a) Incorrect. AT&T is a telecom company, not wind energy.
- (b) Incorrect. Chevron is an oil company, not a chip maker.
- (c) CORRECT. Chevron-Oil, AT&T-Telecom, AMD-Microprocessors, Enercon-Wind.
- (d) Incorrect. Chevron is not a chip maker and AT&T is not a wind firm.
Key point
Chevron = oil; AT&T = telecom; AMD = microprocessors; Enercon = wind turbines.
Remember
Enercon makes wind turbines; AMD makes microprocessors.
Common mistakes
- Guessing Enercon is an oil or power utility because of 'Ener-'.
- Not knowing AMD makes processors.
- Skipping the easy anchors — Chevron-oil fixes A-2 instantly.
Exam tip
Use two sure pairs (Chevron-oil, AMD-chips) to eliminate 3 options.
