Ms. valentino could tell from the first day of school that javier was going to be one of her struggling latino students. he came to school wearing worn clothes. no parent accompanied him, and he acted withdrawn and shy. by the end of the first grading period, she confirmed her impressions. javier's grades were low. this scenario most likely illustrates:

Self-fulfilling prophecy.

Explanation:

Self-fulfilling prophecy or 'placebo effect' is the effect in which false beliefs about own-self or others come true. In this, a person expects something for his/her future which comes true because of his/her belief of it becoming true.

The concept of self-fulfilling prophecies was first developed by Robert Merton.

Pygmalion Effect in self-fulfilling prophecy is the effect that our expectation for others come true.

In the given scenario, Ms. Valentino holds the expectations for Javier that he won't be able to do good in her Latino class. This expectation of Ms. Valentino eventually comes true when Javier scored low.

So, the correct answer is 'Self-fulfilling prophecy'.
