B No.
This question focuses on vocabulary recognition and understanding the meaning of a specific word. The core concept being tested here is whether the student has encountered or can deduce the meaning of the word ‘riwdu’. Since ‘riwdu’ is not a standard English word, this question might be designed to assess general knowledge, critical thinking, or perhaps if it’s a trick question. A student should approach this by first attempting to recall the word from their existing vocabulary. If the word is unfamiliar, they should consider if it might be a typo, an acronym, a word from another language, or a made-up word. The options ‘Yes’ and ‘No’ directly address familiarity, so the primary skill is simply knowing or not knowing the word. This type of question helps build awareness of the vastness of language and the importance of precise vocabulary.
