When parallel lines are cut by a transversal (such as segment PR in this problem), “alternate interior angles” are congruent.
In this problem, ∠y and ∠4 are alternate interior angles, and so you can conclude that they are congruent.

Directions:Read the passages and choose the best answer to each question.PassageThe Earth’s magnetic field is one of its most significant natural phenomena. For centuries, the field has been used to aid navigation and exploration, and has been vital to many major discoveries. The magnetic field of the Earth extends several thousands of miles into space. It has the effect of shielding the Earth from solar wind, protecting the planet from dangerous high-energy particles and radiation. The exact source of the Earth’s magnetic field is not certain. The following two Scientists attempt to explain the phenomenon.Scientist 1The Earth’s magnetic field is similar to that of a bar magnet tilted 11 degrees from the spin axis of the Earth.The magnetic field of a bar magnet, or any other type of permanent magnet, is created by the coordinated motions of electrons within iron atoms. It is widely accepted that the Earth’s core consists of metals. The inner core is 70% as wide as the moon and consists of a solid iron ball, which would exhibit properties of ferromagnetism (the natural magnetic tendency of iron). The core has its own rotation and is surrounded by a “sea” of molten rock. The magnetic field grows and wanes, and the Earth’s poles drift and occasionally flip as the rotation of the core changes. The poles of the magnetic field have “flipped” many times due to the fluctuations in the rotation of the solid inner core. Other fluctuations in the magnetic field that can occur on a daily basis are largely the result of interference by solar wind.Scientist 2The Earth’s magnetic field is attributed to a dynamo effect of circulating electric current in the molten outer core. Electric currents cause magnetic fields; therefore, the circulating electric currents in the Earth’s molten metallic core are the origin of the magnetic field. When conducting fluid flows across an existing magnetic field, electric currents are induced, creating another magnetic field. When this magnetic field reinforces the original magnetic field, a dynamo is created which sustains itself.Sitting atop the hot, iron inner core, the Earth’s molten outer core churns and moves. The outer core also has cyclones or whirlpools powered by the Coriolis effects of Earth’s rotation. These complex and unpredictable motions generate the fluctuating magnetic field. The outer core is seething, swirling, and turbulent, which has been detected by the constant changes and reversals in polarity throughout the planet’s history. Further, iron has a special characteristic.When it is hotter than 1043 K, its Curie temperature, iron loses its magnetic properties. Therefore the Earth’s magnetic field is caused not by magnetised iron deposits, but mostly by electric currents in the liquid outer core.Q.Suppose a new type of sensor was invented that could detect electric currents in the outer core. This new technology would

Directions:Read the passage and choose the best answer to each question.PassageWater pressure influences the rate at which water flows. As water pressure increases, so does the rate of flow. Water pressure can be defined as the amount of force that the water exerts on the container it is in. The more water that is in the container, the greater the water pressure will be. Some students conducted the following experiment:ExperimentStudents used tacks to punch holes in an empty plastic 2-liter bottle. The students created 4 holes, each 1-inch apart, from top to bottom. The tacks were left in each hole as the hole was created. The bottle was filled to the top with water and placed on a table. An 8 × 9-inch pan with a piece of blotting paper was placed lengthwise in front of the bottle. A ruler was placed in the pan to measure the spot at which the water stream touched the paper (range of water stream). The students removed the tack nearest the top of the bottle and marked the spot where the water stream touched the paper (range of water stream). The tack was then replaced, the bottle was filled to the top, and the next tack was removed.The spot where the water stream touched the paper was measured. Rate of flow was indicated by the length of the water stream. This procedure was repeated a total of 4 times, once for each tack. The results are recorded in Table 1 below.Q.Suppose that the students removed the tacks in order, replaced each tack after measuring the water stream, but did not re-fill the bottle after removing and replacing each tack. According to the passage, the water stream would most likely
