In the sentence "He is one of the boys who does not always speak the truth," the correct verb form should be "do," not "does." Here's why:

1. Understanding the Antecedent of "Who":
• The pronoun "who" refers to its antecedent. In this sentence, "who" refers to "the boys." Therefore, "who" is plural because "the boys" is plural.
2. Subject-Verb Agreement with Relative Pronouns:
• Relative pronouns like "who" take verbs that agree in number with their antecedents. Since "who" refers to the plural noun "boys," the verb that follows should also be plural-“do”.

In the sentence there is a subject-verb agreement issue:

·         Subject Identification: The main subject is "The number," which is singular.

·         Verb Agreement: A singular subject requires a singular verb. Therefore, "are" should be "is."

·         Corrected Sentence: "The number of Pumas... is currently given as fewer than one thousand." 

In the sentence the Error of Dangling Modifier occurs.

First-The sentence starts with the phrase “Having performed” and subject of the phrase “Having performed” is “the board of directors.”

Second-Who performed? -Manager.

              Who awarded?  -Board of directors.

So, the subject of modifier phrase “Having performed” will be “the managers.”  

·  The original sentence suggests two actions:

1. The thief stole the money.
2. The police caught the thief.

·  In passive voice, we focus on the action being received:
"The thief was caught by the police."

So, "Having stolen the money" describes the thief.

1. Parallel Structure:
• The phrase "as hot as" is used to make a comparison of equal degree.
• When introducing a possible greater degree, "if not hotter than" correctly maintains parallelism.
2. Correct Use of "than":
• In comparisons involving a potential greater degree, "than" must be used (e.g., "hotter than").
• Incorrect: "as hot as, if not hotter, as" (A) – The second "as" should be "than" instead.
3. Use of "any day of this summer":
• "Any day of this summer" is grammatically clearer and more precise than "any day this summer" (which sounds slightly informal).

Thus, option C correctly follows the rules of comparison and maintains proper parallel structure.

·  Independent Clauses:

• The sentence contains two independent clauses (complete thoughts):
• Clause 1: "Setting up effective personal evaluation procedures is important to any expanded business."
• Clause 2: "It helps most to place the right person in the right position."
• Since both are complete sentences, they cannot be joined with just a comma (this would be a comma splice).

·  Why a Semicolon (;)?

• A semicolon correctly joins two related independent clauses without using a conjunction (like 'and' or 'but').

Thus, option D is grammatically correct.

Correction of "much rains":

"Rains" (plural) is incorrect with "much" because "rain" is usually uncountable.

The correct phrase is simply "rains" without "much."

Use of a Semicolon (;):

The sentence contains two separate but related ideas:

"During the last rainy season we had to suffer much" (a complete thought).

"Rains came into our rooms through the crevices of our old building" (another complete thought).

A semicolon (;) correctly connects these two clauses instead of using a comma (which would be incorrect).

·  Correction of "imminent" vs. "eminent":

• "Imminent" means about to happen soon (incorrect in this context).
• "Eminent" means famous or well-respected, which correctly describes the cartoonist.

·  Correction of "stay" to "stayed":

• The sentence is in the past tense ("was being read"), so "stayed" (past tense) is the correct verb form.

Here, two error occurs:

The word ‘Among’ is used for expressing more than two or more; whereas ‘Between’ is used for expressing two persons.

Immediate next objects of preposition-Among must be in the form of Objective Case. So, ‘I’ will be replaced with ‘me’ and ‘You’ will remain same as Subjective and Objective form of ‘You’ are same.
