In this passage, Ria and Gargi give their opinions about a new painting by Marcello Vasquez. Ria, ‘The new painting is spectacular! It is certainly the best work ever completed by Marcello Vasquez. I like the new painting for several reasons. First, the painting is large. It almost covers the entire wall! Second, the painting is inexpensive. Normally, a painting like this would cost thousands of dollars. But this painting costs less than $500. Third, the painting is colourful. Red and green dominate the canvas, peppered with bright spots of yellow.’

Gargi, ‘The new painting is horrendous! Marcello Vasquez should be ashamed of his work. I haven’t seen a painting this bad in a long time. I dislike the new painiting for several reasons. First, the painting is far too large. It almost covers the entire wall! I think small paintings are better than large ones. Second, the painting is inexpensive. This tells me that Vasquez must have been unable to sell the painting for a higher price. Now, he is desperate. As a result, it appears he is trying to give the painting away. Third the painting is colourful. Although I usually like a painting to be colourful. Although I usually like a painting to be colourful, I strongly dislike the colours Vasquez uses.
