Solution : The correct choice is the fourth option.

The sentence is grammatically correct and conveys the intended meaning that the new lecturer is popular with most of the class.

Therefore, there are no errors in the sentence.

Correct Answer: $2(a+b+c)$

Solution : $4b^2c^2-(b^2+c^2-a^2)^2$
$=(2bc)^2-(b^2+c^2-a^2)^2$
$=(2bc+b^2+c^2-a^2)(2bc-b^2-c^2+a^2)$
$=((b + c)^2-a^2)(a^2-(b^2+ c^2-2bc))$
$=(b + c + a) (b + c -a) (a^2 -(b-c)^2)$
$=(b+ c+a) (b + c -a) (a + b -c) (a -b + c)$
So, the required sum of factors is given as $b+c+a+b+c-a+a+b-c+a-b+ c=2(a+b+c)$
Hence, the

Correct Answer: Micro-operation

Solution : The correct answer is Micro-operation.

A micro-operation is an operation performed on data stored in registers in computer architecture and digital design. Micro-operations are fundamental operations that alter register contents at a very low level and they are often employed in the control and data

Correct Answer: Zymase

Solution : The correct option is zymase.

Zymase is an enzyme complex present in yeast cells that plays an important part in the fermentation process. It catalyses the transformation of glucose and fructose (simple sugars) into ethanol (alcohol) and CO2. This biochemical reaction is essential in the

Correct Answer: $\frac{1}{35}$

Solution : Let the required fraction be $x$.
As per the question,
$\frac{x}{\frac{1}{27}}=\frac{\frac{3}{7}}{\frac{5}{9}}$
⇒ $27x=\frac{27}{35}$
$\therefore x=\frac{1}{35}$
Hence, the correct answer is $\frac{1}{35}$.

Correct Answer: (2)

Solution : The sentence can be improved using the second option.

The presence of "as though" indicates that the sentence is in a subjunctive mood. The verb "had" in the past perfect tense is used in the subjunctive mood to express a hypothetical or imaginary situation that

Correct Answer: $64 \sqrt{3} \mathrm{~cm}^2$

Solution : Given: Sides of the triangle = 16 cm
Area of an equilateral triangle with sides $a$ = $\frac{\sqrt3}{4} (a)^2$
$=\frac{\sqrt3}{4}\times 16\times 16$
$= 64\sqrt{3}$
Hence, the correct answer is $64\sqrt3\ \mathrm{cm^2}$.

Correct Answer: its boiling point

Solution : The correct answer is its boiling point.

Because of its low boiling point of 78°C, distilling alcohol yields a much stronger solution than wine or beer. Because they are less polar than water, drinking alcohol (ethanol), and many other simple alcohols are more
