Explanation

It is the worst film that I have ever seen.

یہ سب سے بری فلم ہے جو میں نے کبھی دیکھی ہے۔

"The worst" is used to describe something as the lowest in quality compared to all others.

Explanation

Solution

• 13 ÷ 2 = 6, remainder 1

• 6 ÷ 2 = 3, remainder 0

• 3 ÷ 2 = 1, remainder 1

• 1 ÷ 2 = 0, remainder 1

Reading the remainders from bottom to top: 1101

So, 13 in binary = 1101.

Explanation

"The petrol boat picked up signals of a ship in distress."

• "Distress" is a noun that refers to a state of danger or emergency.

• "Distressed" is an adjective, but it doesn’t fit the grammatical structure of the sentence.

• "Distressing" is a present participle/adjective that refers to something causing distress, but here we need the noun "distress".

Explanation

"As it was a minor offence, the traffic policeman let him off with a warning."

• "Offence" (noun) means a violation or a wrongdoing, especially of a law or rule.

• The sentence is talking about a small violation, so "minor offence" is the correct phrase.

Explanation

"Wise people do not spend their money foolishly."

• "Wise" is an adjective describing people.

• We use adjectives before nouns (e.g., wise people).

• "Wisely" is an adverb, and "wisdom" is a noun — both do not fit here.

Explanation

"An honest person always speaks the truth."

• "Truth" is a noun and is the correct object of the verb "speaks".

• "True" is an adjective, and "truly" is an adverb — neither fits grammatically here.

Explanation

"I laughed at him for making a silly mistake."

• "Laughed at" is the correct phrase used when you are mocking 

• "For" is used to explain the reason for the action (in this case, making a silly mistake).

Explanation

We are told:

• Circumference of a circle = a

• Area of the circle = b

• And a = b

We know the formulas:

• Circumference:

  $$a = 2pi r$$
  

• Area:

  $$b=\pi r^2$$r=0orr=

Since $a = b$, set the formulas equal:

$$2pi r = pi r^2$$

Divide both sides by $pi$:

$$2r = r^2$$

Rearrange:

$$r^2 - 2r = 0 Rightarrow r(r - 2) = 0$$

So the solutions are:

r=0 or r=2
