* Drag the correct answer into all target fields

A new robotic arm which is controlled by thought has been developed by researchers in the United States. The team placed two microelectrodes into the brain of a woman who is paralysed from the neck down. These were then connected to the arm through a computer running a complex program - one which translated the signals in the same way that a healthy brain does. Although the woman was not able to control the hand at first, after weeks of training she was , and with a level of control and flexibility unseen before. It is this which shows the greatest scientific advance and, as a result, experts are calling it a remarkable achievement. Some suggest that such developments could end up helping many of those like the woman in the experiment to lead fewer challenging lives in the future.

which had been which was fortunately precisely going through able to control the hand microelectrodes

Result:

A.I. Explanation:

Correct answer: microelectrodes
Explanation: The term 'microelectrodes' is a noun that directly refers to the devices placed in the woman's brain. It fits grammatically as the subject of the sentence and is contextually relevant as it describes the technology used in the experiment.
Meaning: 'Microelectrodes' are small electrodes used to detect electrical activity in the brain.
Wrong options:
able to control the hand: This phrase describes an action and does not fit as a noun in this context.
going through: This phrase suggests a process or action, which does not fit as a noun here.
which had been: This phrase is a relative clause and does not serve as a noun, making it grammatically incorrect.

fortunately: This adverb expresses a positive outcome but does not fit as a noun in this context.
Correct answer: which was
Explanation: The phrase 'which was' serves as a relative clause that provides additional information about the computer. It fits grammatically as it connects the noun 'computer' to the description of its function.
Meaning: 'Which was' introduces a clause that describes the computer as running a complex program.
Wrong options:
able to control the hand: This phrase describes an ability and does not fit grammatically as a relative clause.
going through: This phrase suggests an action and does not function as a relative clause.
microelectrodes: This noun does not fit as it does not relate to the description of the computer.
precisely: This adverb does not fit as it does not serve as a relative clause.
which had been: This phrase is a relative clause but does not fit the context of describing the computer's current state.
fortunately: This adverb does not fit as it does not serve as a relative clause.
Correct answer: able to control the hand
Explanation: The phrase 'able to control the hand' describes the woman's newfound ability and fits grammatically as a predicate complement. It is contextually relevant as it highlights her progress after training.
Meaning: This phrase indicates that the woman gained the ability to manipulate the robotic hand.
Wrong options:
going through: This phrase suggests a process and does not describe an ability, making it grammatically incorrect.
microelectrodes: This noun does not relate to the woman's ability and does not fit contextually.
which had been: This phrase is a relative clause and does not describe an ability, making it inappropriate here.
precisely: This adverb does not fit as it does not describe an ability.
which was: This phrase is a relative clause and does not convey the woman's ability.
fortunately: This adverb does not describe an ability and is not relevant in this context.
Correct answer: which had been
Explanation: The phrase 'which had been' serves as a relative clause that provides additional information about the level of control and flexibility. It fits grammatically as it connects to the previous statement about her control.
Meaning: 'Which had been' introduces a clause that describes the previously unseen level of control.
Wrong options:
able to control the hand: This phrase describes an ability and does not fit as a relative clause.
going through: This phrase suggests an action and does not function as a relative clause.
microelectrodes: This noun does not relate to the description of control and does not fit contextually.
precisely: This adverb does not fit as it does not serve as a relative clause.
which was: This phrase is a relative clause but does not convey the idea of something previously unseen.
fortunately: This adverb does not fit as it does not serve as a relative clause.
