The following is an excerpt from Arthur Young's treatise on enclosure- "Respecting open field lands, the quantity of labour in them is not comparable to that of enclosures; for, not to speak of the great numbers of men that in enclosed countries are constantly employed in winter in hedging and ditching, what comparison can there be between the open field system of one half or a third of the lands being in fallow, receiving only three ploughing; and the same portion now tilled four, five, or six times by Midsummer, then sown with turnips, those hand-hoed twice, and then drawn by hand, and carted to stalls for beasts; or else hurdled out in portions for fattening sheep! What a scarcity of employment in one case, what a variety in the other!"Based on this passage, it is reasonable to conclude that Young believed that _________.

As per the question, it would be logical to conclude that Young believed 'the enclosure system was more labor-intensive than the conventional open-field system' which is reflected by the statement 'the quantity....enclosures', 'what comparison...fallow', etc.

Arthur Young's treatise emphasizes the idea of the enclosure system being more intensive as it limits the owner's use of the land which is contradictory to the traditional open-field system that proposes common rights to the owners without any restrictions. Thus, Young believes that the enclosure system becomes more labor-intensive as compared to the traditional open-field system as the former(enclosure system) restricts the traditional rights of the owner on the land that gives the labors necessary freedom to work upon it. However, enclosure system outcast the landless labors from the rural areas and forced them to migrate.
