Question

staar passage practice:
directions: read the article “a method for mastery.” then, answer the questions that follow.
(1) in traditional schooling, time is a constant and understanding is a variable, its a familiar scene to most families who have students in america’s public schools. (2) a fifth - grade class will spend a set number of days on prime factorization and then move on to study greatest common factors — whether or not every student is ready. (3) if a student turns in shoddy work in a flipped mastery class, they can’t move on to the next level, nor can he give up on the objective he has to meet learn.
(4) but their is another way to look at schooling — through the lens of a method called “mastery learning” in which the student’s understanding of a subject is a constant and time is a variable. (5) in these classes, when each fifth grader masters prime factorization, for instance, he moves on to greatest common factors, each at his own pace. (6) it is not a new idea. (7) it was briefly popular in the 1920s, and was revived by benjamin bloom in his paper “learning for mastery” in 1968.
(8) one of the advantages of mastery learning is that the student, not the teacher, leads — and we know that people learn far better when they are actively involved. (9) the teacher provides materials, tools and constant support.
(9) mastery also rewards students for actual learning. (10) a student cannot simply turn in a shoddy paper, take the d, and move on. (11) if she turns in shoddy work, she can’t move on. (12) she has to keep trying until she demonstrates she fully understands.
what revision, if any, is needed to sentence 1?
○ change who to whom
○ remove the comma after schooling
○ change its to it’s
○ capitalizing time and understanding
○ no revision is necessary for this sentence.

Explanation:

To determine the revision for sentence 1, we analyze the possessive form. The sentence is "In traditional schooling, time is a constant and understanding is a variable, its a familiar scene...". The word "its" here is incorrect as it should be the contraction "it's" (meaning "it is") to show "it is a familiar scene". So the correct revision is to change "its" to "it's".

Answer:

Change its to it's
