Along with the four language skills, exams explicitly test two systems. Which are they?

• A. Grammar and Phonology
• B. Grammar and Vocabulary
• C. Phonology and Discourse
• D. Vocabulary and Syntax

Answer: (B)

Exams look for how well you control two language systems in addition to your ability with the four skills. The two systems are grammar and vocabulary. Grammar covers the rules and patterns that govern sentence structure—tenses, articles, prepositions, word order, agreement—so your output is accurate and well-formed. Vocabulary focuses on the range and precision of word knowledge—using the right words, appropriate collocations, and correct word forms for different contexts. Together, strong grammar and vocabulary show you can express ideas clearly and accurately, beyond just performing the language tasks.

Phonology relates to sound and pronunciation, which isn’t treated as one of the two systems here. Discourse concerns how ideas are organized across larger pieces of text, which is important but generally falls under overall language use rather than a separate system alongside grammar and vocabulary. Syntax is essentially a part of grammar, so choosing that wouldn’t represent a separate system.
