View answer & explanation

Correct answer

Answer: (a)A.

Symbiotic

Why this answer is correct

The logic follows here is:

Given four words: Symbiotic, Systematic, Seismic, Symbiosis.

After interchange first and last letters of the given words:

  1. Symbiotic → Cymbiotis 2. Systematic → Cystematis 3. Seismic → Ceismis 4. Symbiosis → Symbiosis

Arranging in ascending order:

Ceismis → Cymbiotis → Cystematis → Symbiosis

After arranging in ascending order, the second will be Cymbiotis, and it is the interchanged word of Symbiotic**.**

Hence, "Symbiotic**"** is the correct answer.

Question 64

  4. DOption (d)

    If neither I nor II follows

View answer & explanation

Correct answer

Answer: (a)A.

If only Conclusion I follows

Why this answer is correct

Given:

Statements:

I: Dengue is spread by mosquitoes.

II: Plague is spread by fleas.

Conclusion:

I. Pest control is important → True (Because, if pest control is not done, then the number of pests will be increased, and diseases are also increased).

II. Killing a living organism is a sin → False (Because, there is no statement given about killing of any living organism).

Hence, "If only Conclusion I follows" is the correct answer.
