Problem: OPTIONS:
- left ventricle
- left bivalve
- left atrium
- right atrium
Q: Answer the following question given this paragraph: Blood from the body enters the right atrium of the heart. The right atrium pumps the blood to the right ventricle, which pumps it to the lungs. This loop is represented by the blue arrows in Figure above . Q: Blood from the body enters what chamber of the heart before it is pumped to the right ventricle and then to the lungs? A:
Answer: right atrium

Problem:OPTIONS:
- greenhouse gases
- fracking disaster
- algal bloom
- oil spill

Answer the following question given this paragraph: Oil spills are another source of ocean pollution. To get at oil buried beneath the seafloor, oil rigs are built in the oceans. These rigs pump oil from beneath the ocean floor. Huge ocean tankers carry oil around the world. If something goes wrong with a rig on a tanker, millions of barrels of oil may end up in the water. The oil may coat and kill ocean animals. Some of the oil will wash ashore. This oil may destroy coastal wetlands and ruin beaches. Figure below shows an oil spill on a beach. The oil washed ashore after a deadly oil rig explosion in the Gulf of Mexico in 2010. Q: A recent deadly explosion in the gulf of mexico exemplified what source of ocean pollution? A:
****
A: oil spill

Answer the following question given this paragraph: Mountain streams may erode waterfalls. A waterfall forms where a stream flows from an area of harder to softer rock ( Figure below ). The water erodes the softer rock faster than the harder rock. This causes the stream bed to drop down, like a step. This creates a waterfall. As erosion continues, the waterfall gradually moves upstream. Q: What process is involved in the formation of a waterfall, when a stream flows from an area of harder to softer rock? A:
OPTIONS:
- calcification
- migration
- evaporation
- erosion
erosion

Answer the following question given this paragraph: To understand the double slit interference pattern, we consider how two waves travel from the slits to the screen, as illustrated in Figure 27.13. Each slit is a different distance from a given point on the screen. Thus different numbers of wavelengths fit into each path. Waves start out from the slits in phase (crest to crest), but they may end up out of phase (crest to trough) at the screen if the paths differ in length by half a wavelength, interfering destructively as shown in Figure 27.13(a). If the paths differ by a whole wavelength, then the waves arrive in phase (crest to crest) at the screen, interfering constructively as shown in. Q: What kind of interference is observed when the paths differ by a whole wavelength, and the waves arrive in phase? A:
OPTIONS:
- necessary interference
- non-interference
- spontaneous interference
- constructive interference

Answer: constructive interference
