The time estimates obtained from four contractors (P, Q, R and S) for executing a particular job are as under:
\[\begin{array}{|c|c|c|c|} \hline \textbf{Contractor} & \textbf{Optimistic time, $t_o$} & \textbf{Most likely time, $t_m$} & \textbf{Pessimistic time, $t_p$} \\ \hline \text{P} & 5 & 10 & 13 \\ \hline \text{Q} & 6 & 9 & 12 \\ \hline \text{R} & 5 & 10 & 14 \\ \hline \text{S} & 4 & 10 & 13 \\ \hline \end{array}\]

- A construction project consists of four activities. The quantity of work, manpower requirement, and the productivity of the activities are listed in the table below. The interrelationship between the activities are also mentioned in the table. The construction project will start on January 29. Assume no holidays for the entire duration of the project. The project will finish on February \underline{\hspace{1cm}} [mention date in number].\[\begin{array}{|c|c|c|c|c|} \hline Activity & Quantity (cu.m) & Manpower (persons) & Productivity (cu.m/man-day) & Immediate Successor Activity \\ \hline \text{A} & \text{96} & \text{8} & \text{3} & \text{C} \\ \hline \text{B} & \text{252} & \text{7} & \text{4} & \text{C \} & \text{D} \\ \hline \text{C} & \text{275} & \text{5} & \text{5} & \text{Nil} \\ \hline \text{D} & \text{126} & \text{6} & \text{3} & \text{Nil} \\ \hline \end{array}\]

Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
Statement:
P. At once, without thinking much, people rushed towards the city in hordes with the sole aim of grabbing as much gold as they could.
Q. However, little did they realize about the impending hardships they would have to face on their way to the city: miles of mud, unfriendly forests, hungry beasts, and inimical local lords—all of which would reduce their chances of getting gold to almost zero.
R. All of them thought that easily they could lay their hands on gold and become wealthy overnight.
S. About a hundred years ago, the news that gold had been discovered in Kolar spread like wildfire and the whole State was in raptures.
