A new satellite sweeping over the poles at altitudes of up to 32,000 miles is called POLAR, giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.(A) A new satellite sweeping over the poles at altitudes of up to 32,000 miles is called POLAR, giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.
(B) A new satellite called POLAR that is giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, sweeping over the poles at altitudes of up to 32,000 miles.
(C) Scientists are getting their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, from a new satellite sweeping over the poles at altitudes of up to 32,000 miles called POLAR.
(D) Sweeping over the poles at altitudes of up to 32,000 miles, a new satellite called POLAR is giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.
(E) Sweeping over the poles at altitudes of up to 32,000 miles, scientists’ best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, is coming from a new satellite called POLAR.
Hello all,
I have created a breakup of the original option as follows:
A new satellite- Subject 1
Sweeping over the poles at altitudes of 32000 miles - Verb ing modifier modifying A new satellite.
is called POLAR- Verb for subject 1
giving scientists their best look yet(shows that till now) at the magnetosphere -Verb ing modifier which modifies the action is called (wrong in this sentence)
the region of space under the invisible influence of Earth...... modifier explaining Magnetosphere.
In this sentence the Verb ing modifier is wrong because there is no action it can modify. Reasons as follows:
A new satellite is called - action of calling is not performed by the Satellite, so the verb ing modifier cannot modify the action.Option A is wrong for all the above mentioned reasons.
Option B: can be directly eliminated because of the SV agreement issue (A new satellite has no verb) but the explanation as follows:
POLAR that is...........their best look yet at the magnetosphere
Sweeping over the poles modifies the clause "that is giving scientists" that--->POLAR
POLAR is giving the scientists their best look
Polar is sweeping over the poles...... looks like the modifier and the verb makes sense modifier presents additional info about the POLAR
usage of their-> their should refer to scientists ideally but the usage in the option "that is giving scientists scientists best look yet at the magnetospehere" causes confusion here.
(c) the usage of the "called POLAR" seems wrong called acts as noun modifer and should be closer to the noun"a new satellite".
(D) Sweeping.......... defines a new satellite - Verb ing modifier modifying a noun
called POLAR modifies the closest noun a new satellite.
is giving -Verb (rest all is correct)
(E) Verb ing modifier modifies scientists best look -- wrong
is coming from a new satellite looks correct in this option.
Please review.
