In the following sentence improvement question, identify the part of the sentence that contains an error and select the correct option. If there is no error, select "No Error". Sentence: Water was dripping of the trees, and the grass was wet.

Introduction / Context:
This question belongs to the category of error spotting in English grammar. The sentence describes a scene after rainfall or dew, where water is dripping and the grass is wet. The candidate must examine each underlined or numbered part to find the grammatical or idiomatic error. Such questions focus on correct preposition use, subject–verb agreement, tense, and standard idiomatic expressions in English.

Given Data / Assumptions:
- The sentence is divided into three parts plus a “No Error” option. - Full sentence: “Water was dripping of the trees, and the grass was wet.” - Part 1: “Water was dripping” - Part 2: “of the trees, and” - Part 3: “the grass was wet.” - Standard English prepositions and verb patterns are assumed.

Concept / Approach:
The key concept here is the correct use of prepositions with the verb “drip”. In natural English, one says “water was dripping from the trees” or “water was dripping off the trees”. The use of “of” is incorrect in this context. The rest of the sentence uses a past continuous form plus a simple past clause joined by “and”, which is grammatically acceptable. Therefore, attention must be directed to the preposition in part 2.

Step-by-Step Solution:
Step 1: Analyse part 1, “Water was dripping”. This is grammatically correct past continuous tense, describing ongoing action in the past. Step 2: Examine part 2, “of the trees, and”. Here, the verb “dripping” is followed by the preposition “of”, which sounds unnatural and wrong in standard English usage. Step 3: Recall the correct prepositional phrase. We normally say “dripping from the trees” or “dripping off the trees”. Both “from” and “off” express source or origin of the dripping water. The preposition “of” does not fit this meaning. Step 4: Check part 3, “the grass was wet.” This is a simple, correct past tense clause with no grammatical problem. Step 5: Since the only faulty element is the preposition “of” in part 2, we identify part 2 as the segment containing the error.

Verification / Alternative check:
Rewrite the sentence with the correction: “Water was dripping from the trees, and the grass was wet.” This version sounds natural and grammatically correct. No further changes are needed in parts 1 and 3. If we test the “No Error” option, we see that at least one edit is necessary, so “No Error” cannot be the right answer. The diagnosis that only part 2 is wrong therefore stands.

Why Other Options Are Wrong:
Part 1: “Water was dripping” correctly uses the past continuous to describe an ongoing action. Part 3: “the grass was wet” is a standard simple past clause and agrees with the context. Part 4 (No Error): Selecting this would ignore the incorrect preposition “of”. Error cannot be determined: This is incorrect because the grammatical issue is clearly identifiable.

Common Pitfalls:
A common mistake is to read quickly and accept unusual preposition use as possibly regional or stylistic. However, examination questions typically expect standard international usage. Another pitfall is overanalyzing parts 1 and 3 and imagining tense problems where none exist. Systematically checking each part and focusing on collocations like “drip from” or “drip off” helps avoid such confusion.

Final Answer:
The error lies in Part 2: of the trees, and, where the preposition “of” should be replaced by “from” or “off”.
