OFFICIAL EXPLANATION

A major medical center recommends that doctors take a brief nap during long shifts, because studies show that if shift-workers lose sleep one-night and  accumulated a sleep deficit on the following days, their reaction-time and judgment will be impaired .

A. accumulated a sleep deficit on the following days, their reaction-time and judgment will be impaired

Incorrect.

This answer choice is grammatically incorrect. We identify the sentence as a Conditional 1 sentence by the use of Present Simple in the first verb in the condition part ( if shift-workers  lose  ) and by the use of the Future tense in the result part ( will be impaired ). However, the second verb in the condition part ( accumulated ), which should also be in the Present Simple tense, is in the Past Simple.

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign: If/Unless

B. accumulate a sleep deficit on the following days, their reaction-time and judgment will be impaired

This answer choice corrects the Conditionals mistake in the original question, by changing the tense of the second verb in the condition part of the sentence from Past Simple (accumulated) to Present Simple (accumulate).

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign:

If/Unless

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign:

If/Unless

C. accumulate a sleep deficit on the following days, their reaction-time and judgment was impaired

Incorrect.

While this answer choice corrects the original Conditionals mistake in the original question, it creates a new Conditionals mistake. By changing  will be impaired  to  was impaired , this answer choice incorrectly uses the Past Simple in the result part of a Conditional 1 sentence.

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign: If/Unless

D. accumulated a sleep deficit on the following days, it impaired their reaction-time and judgment

Incorrect.

This answer choice repeats the original Conditionals mistake. We identify the sentence as a Conditional 1 sentence by the use of Present Simple in the first verb in the condition part ( if shift-workers  lose  ) and by the use of the Future tense in the result part ( will be impaired ). However, the second verb in the condition part ( accumulated ), which should also be in the Present Simple tense, is in the Past Simple.

Moreover, the result part of a Conditional 1 should be in the Present Simple or Future, but this answer choice incorrectly uses the Past Simple ( impaired ).

E. accumulate a sleep deficit on the following days, this impairs one's reaction-time and judgment

Incorrect.

While this answer choice corrects the original Conditionals mistake, it creates a new grammatical mistake. The pronoun  one  refers only to itself. However, the noun referred to in the earlier part of the sentence is not one but  shift workers . The correct pronoun in this case would be  their .

A major medical center recommends that doctors take a brief nap during long shifts, because studies show that if shift-workers lose sleep one-night and accumulated a sleep deficit on the following days, their reaction-time and judgment will be impaired.

A.  accumulated  a sleep deficit on the following days, their reaction-time and judgment will be impaired -  Accumlated must be parallel to lose ,you accumlate a sleep deficit after loosing sleep so accumlate(simple present tense) needs to be used 
B. accumulate a sleep deficit on the following days, their reaction-time and judgment will be impaired - Correct answer 
C. accumulate a sleep deficit on the following days, their reaction-time and judgment  was impaired  -  was impaired is wrong 
D. accumulated a sleep deficit on the following days, it impaired their reaction-time and judgment -  Repeats the tense error in Option A , pronoun "it" has no antecedent 
E. accumulate a sleep deficit on the following days,  this  impairs one's reaction-time and judgment -  the pronoun this cannot refer to the entire action of losing ones sleep and accumlating sleep deficit

B. accumulate a sleep deficit on the following days, their reaction-time and judgment will be impaired

D. accumulated a sleep deficit on the following days, it impaired their reaction-time and judgment
E. accumulate a sleep deficit on the following days, this impairs one's reaction-time and judgment

We look directly before the underlined portion for our first split; Accumulated/Accumulate. Lose sleep and accumulated sleep deficit is not parallel. Eliminate A/D.
Next we need a future tense for "impaired". Only answer choice that fits is "B"

..........lose.............and...........accumulated ................... - not in parallel

lose in present form whereas accumulated in past form, 
so eliminate A & D

.....if.........present form..........., .........present form or future form............
In C second portion of If clause is in past form, Eliminate

In E this refers to which? not clear, so Eliminate

Answer B

jrk23 · Answer

- Use of this and One's is not correct as Shift workers is plural.

In the Non-Underlined part "lose" is in present tense so we need present tense in underlined part to make that parallel.

We are Left with "b" and "C".

"C"- is wrong becuase all are in present no need to use "Was".
