A group of students in an American village has been selected for testing a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity of current computer chips.
A. has been selected for testing a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity of current computer chips
B. have been selected to test a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity used by current computer chips
C. has been selected to test a new low-cost electronic notepad to be built on a new class of green microchips, which are also power-stingy and which use a fraction of the electricity used by current computer chips
D. have been selected for testing a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity of current computer chips
E. has been selected to test a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity used by current computer chips
IMO EA group will be singular here so options with have is out. Hence remain A, C,E.
To test shows intention hence A is out.
C. has been selected to test a new low-cost electronic notepad to be built on a new class of green microchips, which are also power-stingy and which use a fraction of the electricity used by current computer chips -- It says the chip is yet to be built ,that's not the intended meaning. If it's yet to be built how are we testing it? Hence out.
E. has been selected to test a new low-cost electronic notepad being built around a new class of green, power-stingy microchips that use a fraction of the electricity used by current computer chips-- Correct choice
