A sentence is given with an underlined part that may need improvement. Choose the alternative that best improves the underlined part. In case no improvement is needed, select the option indicating No improvement. Sentence: As you grow older, you will find that these all difficulties may be overcome by patience.

Introduction / Context:
This sentence improvement question examines correct word order, passive voice formation, and preposition choice in English. The sentence offers advice about how patience helps in dealing with difficulties. The underlined portion contains a word order error and an incomplete passive structure, both of which must be corrected for the sentence to sound natural and grammatically accurate.

Given Data / Assumptions:
The full sentence is As you grow older, you will find that these all difficulties may be overcome by patience. The underlined part is these all difficulties may be overcome by patience. The answer choices include several rephrasings: these all difficulties may overcome with patience, all these difficulties may overcome through patience, all these difficulties may be overcome with patience, and No improvement.

Concept / Approach:
First, in English the natural order is all these difficulties, not these all difficulties. Second, the passive form requires the auxiliary be plus the past participle of the verb. Here, may be overcome is the correct passive form, while may overcome lacks the auxiliary be and is therefore incorrect. Third, with patience is the common collocation when referring to the means or quality needed to deal with problems, while by patience is less natural in this context. Thus, the best improvement must combine all these corrections at once.

Step-by-Step Solution:
Step 1: Correct the word order by placing all before these, forming all these difficulties. Step 2: Ensure the passive voice of overcome is complete by including be, giving may be overcome rather than may overcome. Step 3: Choose the preposition with to show the means or quality by which the difficulties are handled, resulting in with patience. Step 4: Compare the options and find which one contains all these elements together. Step 5: Select all these difficulties may be overcome with patience as the fully correct and natural sounding version.

Verification / Alternative check:
To verify, we can compare a similar structure: All these problems can be solved with patience. This sentence clearly has the same pattern as the corrected version in the question. If we attempt These all problems can solve with patience, the result is ungrammatical because of wrong word order and missing passive auxiliary. The safe model to remember is modal verb plus be plus past participle, for example may be overcome, can be solved, or must be completed. With patience is also a standard expression for the manner or means of dealing with difficulties.

Why Other Options Are Wrong:
These all difficulties may overcome with patience contains wrong word order (these all instead of all these) and an incomplete passive form (may overcome instead of may be overcome).
All these difficulties may overcome through patience still misses the auxiliary be, so the passive structure is incorrect, even though the word order is improved.
No improvement cannot be selected because the original phrase these all difficulties may be overcome by patience has both the word order problem and a less natural preposition choice.

Common Pitfalls:
Candidates often focus on only one aspect of the underlined part and miss other errors. In this case, someone might spot the word order issue but ignore the passive voice, or notice the missing be in some options without seeing the preposition nuance. A good exam strategy is to check each option systematically for subject verb agreement, word order, verb form, and preposition choice before deciding which version is best in both grammar and natural usage.

Final Answer:
The underlined part should be improved to all these difficulties may be overcome with patience.
