The given statement is clearly true.

Clearly, only segment Q fits after the first segment. This eliminates all the options except 1.

Option 2: It is incorrect because it ends in S which ends in 'towards' which can't be used to any statement.

Option 3: It is incorrect for the same reason as option 2.

Option 4: 'towards their plight further worsened' makes no sense; hence it can be eliminated.

Option 5: R is a clear misfit after the first segment; hence it can also be eliminated. Hence, the correct sequence is QSRP.

16-bit processor - 8086/68000/Z8000;

32-bit processor - 80386/80486

You have to consider three things.

1. First, are the bonds polar?

Look at differences in electronegativity and if  it is >0.5, bonds are polar.

2. Second, does the molecule have unshared electron pairs?

If so, they generally lead to a polar molecule.

3. Third, is the molecule symmetric?

If so, then although the bonds may be polar, the symmetry cancels out the individual bond polarity and the molecule is non polar.

CF4 follows all the rules above and has a symmetric distribution of charge, making it nonpolar. The others all have asymmetric charge distributions.

Hence, CF4 represents a Non-polar molecule.
