From the words lettered A to D choose the word or group of words that best completes each of the following sentences.
I want everybody to learn the last ten lines of the poem .... heart

Answer Details

The correct answer is "by". The phrase "learn the last ten lines of the poem" implies that the person wants everyone to memorize the lines. The word "by" is often used to indicate the means or method of doing something, and in this context, it means that the person wants everyone to memorize the lines "by heart" - that is, to memorize them so well that they can recite them from memory without any assistance. Therefore, the complete sentence would read: "I want everybody to learn the last ten lines of the poem by heart."
