The sentence 'I take exercise daily' is in the simple present tense, indicating a habitual action. The correct passive voice form for a simple present tense active sentence is formed using 'is/am/are + past participle'. Therefore, the correct passive sentence is 'Exercise is taken daily by me.' Option C, 'Exercise is being taken daily by me,' is present continuous passive, which implies an action happening right now, not a habitual action. Options A and D are grammatically incorrect due to subject-verb agreement and incorrect verb forms.

The idiom 'Have an axe to grind' means to have a personal motive, often selfish or hidden, for doing or saying something. It implies having a grievance or a private reason to push an agenda, not necessarily a direct dispute with someone. Therefore, option B ('Selfish motive') is the most accurate meaning. Option C ('To have a dispute with someone') is related but less precise, as the idiom focuses more on having a personal agenda or grievance rather than an active dispute.

The phrase 'lesson on [topic]' is standard English usage to indicate the subject matter of the lesson. 'Upon' is not typically used in this context, and 'about' or 'in' are less common and less idiomatic. Therefore, the correct sentence is 'My first lesson on forgiveness came from my mother.'
