Key Points 

• There are two combinations from the given phrases that make meaningful sentences.
• Part B and F connect grammatically and contextually. Part B states ‘Harrison’s project is the world’s first field trial of marine cloud brightening, one of’ which is connected with Part F i.e. ‘several controversial geoengineering technologies that scientists have studied in the laboratory for decades’.
  • ​Part B mentions the first field trial of ‘marine cloud brightening’. Part F mentions ‘one of the controversial geoengineering technologies’. We can infer that F part talks about the marine cloud brightening technology. Thus, B - F is the correct combination.
• Parts C and D connect grammatically and contextually. Part C states ‘Methane is the main component of natural gas, whose popularity as’ which is connected with Part D i.e.’a relatively clean source of fossil energy has soared by more than 50% over the past two decades’.
  • ​Part C talks about ‘Natural gas’. Part D talks about a relatively clean source of fossil energy, and this is contextually related to natural gas which has become popular. The two parts connect grammatically as well. Thus, C - D is the correct combination.

The correct sentences will be:

• Harrison’s project is the world’s first field trial of marine cloud brightening, one of several controversial geoengineering technologies that scientists have studied in the laboratory for decades.
• Methane is the main component of natural gas, whose popularity as a relatively clean source of fossil energy has soared by more than 50% over the past two decades.
