1. We can see a person in the picture. The blues are on/at the background.
(Which preposition do we have to use?)
2. By whom was this painting painted?
3. By whom was this picture painted?
4. By whom was this painting drawn?
5. By whom was this drawing drawn?
6. By whom was this drawing painted?
(Which ones are ungrammatical? Can we use the verb 'draw' with 'painting'? Can we use both 'draw' and 'paint' with 'picture'?)
If it's a painting, it's not a drawing. A picture, though, may be a photograph, a painting, a drawing...
Blues in the background: either in or on, not at.
1. In this case, we should use the preposition "in." We say "the blues are in the background" to indicate that they are located within the background of the picture.
2. The sentence "By whom was this painting painted?" is grammatically correct. It follows the passive voice structure with the subject "this painting" being acted upon by the verb "painted."
3. The sentence "By whom was this picture painted?" is also grammatically correct. The verb "painted" can be used with both "painting" and "picture" to describe the act of creating an artwork.
4. The sentence "By whom was this painting drawn?" is grammatically correct. However, it implies that the artwork in question was created using drawing techniques rather than painting techniques.
5. The sentence "By whom was this drawing drawn?" is grammatically correct. It follows the passive voice structure and accurately describes the act of creating a drawing.
6. The sentence "By whom was this drawing painted?" is grammatically incorrect. Since the verb "paint" specifically refers to the act of applying paint to a surface, it cannot be used to describe the creation of a drawing. The verb "draw" is more appropriate for the act of creating a drawing.
