You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The paraphrase technique differs from the cantus-firmus technique in that the source material, though it still consists of a monophonic original, is embellished, often with ornaments. As in the cantus-firmus technique, the source tune may appear in many voices of the mass.
Several of Josquin's masses feature the paraphrase technique, and they include some of his most famous work including the great Missa Gaudeamus. The relatively early Missa Ave maris stella, which probably dates from his years in the Sistine Chapel choir, paraphrases the Marian antiphon of the same name; it is also one of his shortest masses. The late Missa de Beata Virgine paraphrases plainchants in praise of the Virgin Mary; it is a Lady Mass, a votive mass for Saturday performance, and was his most popular mass in the 16th century.By far the most famous of Josquin's masses using the technique, and one of the most famous mass settings of the entire era, was the Missa pange lingua, based on the hymn by Thomas Aquinas for the Vespers of Corpus Christi. It was probably the last mass that Josquin composed. This mass is an extended fantasia on the tune, using the melody in all voices and in all parts of the mass, in elaborate and ever-changing polyphony. One of the high points of the mass is the et incarnatus est section of the Credo, where the texture becomes homophonic, and the tune appears in the topmost voice; here the portion which would normally set "Sing, O my tongue, of the mystery of the divine body" is instead given the words "And he became incarnate by the Holy Ghost from the Virgin Mary, and was made man.".
Output:
What is the name of the person whose most popular mass in the 16th century was Missa de Beata Virgine?
