                                                      Oceanography
                    Oceanography, the study of the ocean also called marine science, has been attracting
                    scientists’ attention as it holds a profound significance to global warming.  A  Among
                    many reasons, ocean heat content (OHC), the heat stored in the ocean, is what many
                    scientists consider to be of great importance.  B  Absorbing more than 90 percent of the
                    energy of global warming, heat in the ocean causes thermal expansion of seawater,
                    leading to a global sea-level rise.  C  According to scientific research, it is clear that
                    these problems are imminent as the findings indicate that the global sea surface has
                    been rising 3.2 millimeters every year since 1993.  D


                    One of the oceanographic variables used to calculate the OHC is sea surface
                    temperature (SST), which refers to the water temperature 1 to 20 millimeters below
                    the sea surface. Among a variety of techniques for measuring the SST, the most widely
                    available are thermometers and weather satellites. In addition to the sea-level rise, the
                    SST contributes to other phenomena of the Earth’s atmosphere such as the formation
                    of sea fog and sea breezes. The temperature difference between warm water surface
                    and cold air above can produce moisture that becomes condensed into vertically-
                    developed clouds and snow showers.  As the whole global population is vulnerable to
                    rising ocean heat and sea surface temperatures, their causes and consequences ought
                    to be systematically analyzed and addressed.




                  01   The word imminent in paragraph 1 is closest in meaning to

                        A  critical       B  approaching        C  intimidating     D  distant



                  02     Look at the four squares [  ] that indicate where the following sentence could
                        be added to paragraph 1.


                          This phenomenon of rising sea levels is a serious environmental issue because it
                          threatens coastal ecosystems and wildlife populations.


                        Where would the sentence best fit?
                        A  A                B  B                C  C                D  D
