Question: Please answer correctly the following question related to the paragraph below.   Which lake had more phytoplankton?  Scientists studied water stratification in two saltwater lakes. they were trying to find out why the fish population decreased in Long lake, and was very healthy and abundant in Shoal lake. They found out the phenomenon occurred more often in Long lake, leading to very many unpleasant chain effects.  Hint: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers.  Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2]
Answer: Shoal lake

Question: Please answer correctly the following question related to the paragraph below.   Which team had more people with an increased blood flow to the muscles before the match?  There was a soccer match between Red team and Blue team. Blue team got there early, warmed up properly and were ready for the game. Red team arrived late and almost skipped warming up entirely. Costly decision, as it turns out, because they lost.  Hint: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ).
Answer: Blue

Question: Please answer correctly the following question related to the paragraph below.   Which village is managing traffic more efficiently?  Berg village and Hill village are renowned for the high number of cyclists living there. Berg village dealt with many traffic casualties because of narrower streets and lanes, While Hill village had wide streets, more traffic signals and a greater number of cyclists.  Hint: Turner et al (2006) derived crash prediction models for this report’s predecessor and found a pronounced ‘safety in numbers’ effect in the models. Using the crash prediction model for mid-block locations, generic motorist and cyclist volumes can be used to demonstrate the impacts on the expected crash rate of varying motor vehicle and cycle volumes. As shown in figure 2.20, an increase in the proportion of cyclists to the overall traffic volume causes an increase in expected crashes at mid-block locations, but the crash rate increases at a decreasing rate. That is to say, the crash rate per cyclist goes down as the cycle volume increases.
Answer:
Hill
