QUES: Support for the LRC was boosted by the 1901 Taff Vale Case, a dispute between strikers and a railway company that ended with the union being ordered to pay 23,000 damages for a strike. The judgement effectively made strikes illegal since employers could recoup the cost of lost business from the unions. The apparent acquiescence of the Conservative Government of Arthur Balfour to industrial and business interests (traditionally the allies of the Liberal Party in opposition to the Conservative's landed interests) intensified support for the LRC against a government that appeared to have little concern for the industrial proletariat and its problems.
What appeared to be very concerned with the industrial proletariat?

In 1910, over 2 million children in the same age group were employed in the United States. This included children who rolled cigarettes, engaged in factory work, worked as bobbin doffers in textile mills, worked in coal mines and were employed in canneries. Lewis Hine's photographs of child labourers in the 1910s powerfully evoked the plight of working children in the American south. Hines took these photographs between 1908 and 1917 as the staff photographer for the National Child Labor Committee.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did children roll in a factory?
Ah, so.. cigarettes

Question: Psychoactive drugs can impair the judgment of time. Stimulants can lead both humans and rats to overestimate time intervals, while depressants can have the opposite effect. The level of activity in the brain of neurotransmitters such as dopamine and norepinephrine may be the reason for this. Such chemicals will either excite or inhibit the firing of neurons in the brain, with a greater firing rate allowing the brain to register the occurrence of more events within a given interval (speed up time) and a decreased firing rate reducing the brain's capacity to distinguish events occurring within a given interval (slow down time).
Try to answer this question if possible: The level of what is the reason stimulants and depressants change human perceptions of time?
Answer: The level of activity in the brain of neurotransmitters
