Table 2 Signs of $p_{3}^{'}$ and $p_{5}$

	(−)	(+)
$p_{3}^{'}$	$a_{2} < a_{4} a_{5}$	(i) $a_{1} a_{2} > a_{4} a_{5}$ and r is close to R
$p_{3}^{'}$	$a_{2} < a_{4} a_{5}$	(ii) $a_{2} > a_{4} a_{5}$ , $a_{1}$ is close to 1 and r is close to 0
$p_{5}$	$\frac{a_{2}}{l_{5} - l_{2}} < \frac{1 - a_{1}}{l_{1}}$ and r is close to 0	$\frac{a_{2}}{l_{5} - l_{2}} > \frac{1 - a_{1}}{l_{1}}$
