Required ratio = The total sales of branch B2 for both years : The total sales of branch B4 for both years
Required ratio = 140 : 180 = 7 : 9
Hence, the correct answer is 7 : 9.

Correct Answer: crop

Solution : The second option is the correct answer.

Crop up is the correct phrasal verb in this context because it conveys that something might suddenly or unexpectedly appear or emerge.

The meanings of the other options are as follows:

• Fill up doesn't fit the context as it suggests something gradually becoming full, which doesn't convey the sudden or unexpected nature of the appearance of a new flu strain.
• Bring up doesn't convey the idea of something emerging on its own; it implies an intentional action, which is not the intended meaning of this sentence.
• Chop up is also inappropriate because it suggests cutting something into pieces. 

So, the complete sentence is: As global temperatures rise, an untreatable new strain of the flu might crop up at any moment.

Correct Answer: 30 cm

Solution :
Given:
OY = 50 cm and XY = 40 cm
Use the Pythagorean theorem to find the length of OX, which is the radius of the circle [in $\triangle OXY$]
OY² = OX² + XY²
⇒ OX² = OY² – XY²
⇒ OX² = (50)² – (40)²
⇒ OX² = 2500 – 1600 = 900
⇒ OX = $\sqrt{900}$ = 30 cm
Hence, the correct answer is 30 cm.
