In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Example Input: Timothy likes to play sports. He spends his time after school playing basketball and baseball. Sometimes Timothy pretends he is a famous baseball pitcher for his favorite team with his friends. He plays with his friends Mandy and Andrew. Timothy also plays pretend when he is alone. He has an imaginary friend named Sean. Sean is an elephant who watches television with Timothy. Mandy likes playing baseball but she also likes to paint. Mandy's favorite class at school is art. She likes making pictures of flowers. Her teacher says she is a good artist. She painted a picture of a tree for her teacher. There were red and yellow leaves on it. It had apples on it. When Andrew goes home after baseball, he likes to eat a snack. He eats carrots and bananas. If he is a good boy his mom, Mrs. Smith, sometimes gives him milk and cookies. Afterwards, Andrew finishes his homework. <sep>Timothy likes to spend his time after school doing what and with who?<sep>He plays with his friends Mandy and Andrew
Example Output: Yes

Example Input: General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Noether's theorem allows these quantities to be determined from a Lagrangian with translation invariance, but general covariance makes translation invariance into something of a gauge symmetry. The energy and momentum derived within general relativity by Noether's presecriptions do not make a real tensor for this reason. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of coordinates. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field. This approach has been echoed by Lev Landau and Evgeny Lifshitz, and others, and has become standard. The use of non-covariant objects like pseudotensors was heavily criticized in 1917 by Erwin Schrodinger and others. <sep>When did the standard approach to energy momentum become criticized?<sep>1911
Example Output: Yes

Example Input: The first rule is parental.  The primitive monarchy is in the home.  A young baby cries.  The trained nurse turns on the light, lifts the baby, hushes it, sings to it, rocks it, and stills its weeping by caresses and song.  When next the baby is put down to sleep, more cries, more soothing and disturbance, and the setting of a tiny instinct which shall some day be will--the power of control.  The grandmother arrives on the scene.  When baby cries, she plants the little one firmly in its crib, turns down the light, pats and soothes the tiny restless hands that fight the air, watches, waits.  From the crib come whimpers, angry cries, yells, sobs, baby snarls and sniffles that die away in a sleepy infant growl.  Silence, sleep, repose, and the building of life and nerve and muscle in the quiet and the darkness.  The baby has been put in harmony with the laws of nature--the invigoration of fresh air, sleep, stillness--and the little one wakens and grows like a fresh, sweet rose.  The mother, looking on, learns of the ways of God with men. <sep>How many related people are discussed in this passage?<sep>Two people the nurse and the grandmother

No
