SSC CGL Model Paper 5

Concept:Dictionary order is found by comparing letters from left to right.Explanation:All four words start with $\text{Per}$.$\text{Permafrost}$, $\text{Permanence}$, and $\text{Permanent}$ start with $\text{Perma}$.$\text{Permeability}$ starts with $\text{Perme}$.Since $a < e$, $\text{Permeability}$ comes last.Among the remaining three, after $\text{Perma}$, $\text{Permafrost}$ has $f$, while the other two have $n$.So $\text{Permafrost}$ comes first.Between $\text{Permanence}$ and $\text{Permanent}$, compare up to $\text{Permanen}$.The next letter is $c$ in $\text{Permanence}$ and $t$ in $\text{Permanent}$.Since $c < t$, $\text{Permanence}$ comes before $\text{Permanent}$.Thus the order is: iii, i, ii, iv.Answer:The correct sequence is iii, i, ii, iv, which is option D.
