Question

S1: There is still another important characteristic of living things.
S6: And abrupt changes occur too, which are called mutations.
P: One generation is not a perfect copy of the preceding generation.
Q: Plants and animals are not exactly like their parents.
R: That attribute is the capacity to evolve.
S: There is a continual realignment of inherited characteristics.
The proper sequence should be:

• A. P-S-Q-R
• B. R-Q-P-S
• C. Q-S-R-P
• D. R-S-P-Q

Answer 1

The correct option is B R-Q-P-S

The first statement in the sequence should be the one that best connects with S1. It should be a continuation or extension of S1.

R is first in the sequence: S1 says that there is still another important characteristic of living things. R tells us what this characteristic is. It says that the attribute is the capacity to evolve.

R is followed by Q: Q starts to explain R's point. It says that plants and animals are not exactly like their parents.

Q is followed by P: P infers from Q. It says that one generation is not a perfect copy of the preceding generation.

P is followed by S: S further adds to P. It says that there is a continual realignment of inherited characteristics. S6 further adds that there are also abrupt changes which are called mutations.

Thus, the correct sequence is R Q P S. Hence, B is the correct option.
