The restructuring agency explored several alternatives, including complete and partial liquidation of assets, but has not found any feasible solution to the problems faced by the company.

Note :
Parallel structure (in verb tense) should be used when you connect clauses with a coordinating conjunction such as: for, and, nor, or, but, so, or yet.

(A) explored several alternatives, including complete and partial liquidation of assets, but has not found
explored (past) || has not found( present perfect)
(B) had explored several alternatives, which include complete and partial liquidation of assets, but has not found
had explored (past perfect) || has not found (present perfect)
(C) explored several alternatives, including complete and partial liquidation of assets, but did not found
Incorrect (past) tense structure.
The agency did not FIND --- Correct.
The agency did not FOUND -- incorrect. After verb DID, the action verb should be in its base form i.e. FIND
(D) has explored several alternatives, including complete and partial liquidation of assets, but has not found
has explored || has not found -- both present perfect tenses. Correct.
(E) has explored several alternatives, including complete and partial liquidation of assets, but did not find
has explored (present perfect) || did not find ( past)

D

The restructuring agency explored several alternatives, including complete and partial liquidation of assets, but has not found any feasible solution to the problems faced by the company.


(A) explored several alternatives, including complete and partial liquidation of assets, but has not found -> Something explored (past tense) and has not found (present tense), It doesn't make sense. They must be exploring till now. Incorrect.

(B) had explored several alternatives, which include complete and partial liquidation of assets, but has not found -> had explored- we don't see two actions. Incorrect.

(C) explored several alternatives, including complete and partial liquidation of assets, but did not found -> Explored and found both are in past, it doesn't make sense. Intended meaning is solution is yet to be found. Incorrect.

(D) has explored several alternatives, including complete and partial liquidation of assets, but has not found -> It is better. Explored (from past to present) and found (from past to present). Let's keep it.

(E) has explored several alternatives, including complete and partial liquidation of assets, but did not find ->"has Explored" is in present and "did find" is in past, it doesn't make sense. Incorrect.

So, I think D.

The restructuring agency explored several alternatives, including complete and partial liquidation of assets, but has not found any feasible solution to the problems faced by the company.

Error Analysis:- Verb tense "explored" seems to be correct. Intended meaning is Agency explored few alternatives but no feasible solution has been found.. I couldn't see any error in original sentence.

(A) explored several alternatives, including complete and partial liquidation of assets, but has not found
Correct.

(B) had explored several alternatives, which include complete and partial liquidation of assets, but has not found
Incorrect. Past perfect "had explored" isn't required.
(C) explored several alternatives, including complete and partial liquidation of assets, but did not found
Incorrect. "didn't found" is wrong usage. we would require "has found".

(D) has explored several alternatives, including complete and partial liquidation of assets, but has not found
Incorrect. "has explored" seems to be wrong because as per original sentence exploration is completed.

(E) has explored several alternatives, including complete and partial liquidation of assets, but did not find
Incorrect. "didn't find" is incorrect.

IMO A.

The restructuring agency explored several alternatives, including complete and partial liquidation of assets, but has not found any feasible solution to the problems faced by the company.

(A) explored several alternatives, including complete and partial liquidation of assets, but has not found

Tense issue ..

For this question, I followed the consistency of tenses to eliminate the options.



Based on above reasoning, I would go with D.

Official Explanation:

(A) The restructuring agency has done two things which need to be placed in the same tense. Explored in the simple past tense is not consistent with has not found in the present perfect tense. You need to go with the simple past tense did not find to make this correct.

(B) The past perfect tense had explored is not consistent with the present perfect tense has not found.

(C) Did not found is an incorrect phrase—you need the base form of the verb after did not, that is, find and not found (which itself is in the simple past tense).

(D) The correct answer; places both the actions in the present perfect tense.

(E) The present perfect has explored is not consistent with the simple past tense did not find.
