Try to extracxt from the passage why does the James web Telescope rely so heavily on infrared?

Context: high-redshift objects have their visible emissions shifted into the infrared, and therefore their light can be observed today only via infrared astronomy;
infrared light passes more easily through dust clouds than visible light;
colder objects such as debris disks and planets emit most strongly in the infrared;
these infrared bands are difficult to study from the ground or by existing space telescopes such as Hubble.

Answer: It seems from the text that very early and distant objects visibility shifts to infrared and their light can be observed only via infrared
