According to the following text, answer questions 6 and 7. Knowledge does not consist of a series of self-consistent theories that tend to converge in an ideal perspective; it does not consist of a gradual approach to the truth. Rather, knowledge is an ever-increasing ocean of incompatible (and perhaps incommensurable) alternatives; every particular theory, every fairy tale, every myth, is part of the whole that forces the rest to a greater articulation, and all of them contribute, through this competitive process, to the development of our knowledge. There is nothing established forever, no point of view can be omitted in a comprehensive explanation (...). Experts and laymen, professionals and dilettantes, builders of utopias and liars, all of them are invited to participate in the debate and to contribute to the enrichment of culture. The task of the scientist should no longer be "the search for truth", or "the glorification of God", or "the systematization of observations" or "the perfecting of predictions." All these things are nothing more than marginal effects of an activity to which his attention is now directed and which consists of "making the weakest cause the strongest cause", as the sophist said, "therefore in supporting the movement of set". 6.- Which of the following options best describes the relationship between the content of the text and the title of the work from which it was extracted? * a) The text introduces the proposal of a new method for scientific research, different from the traditional one
b) The text attacks different ideas about what the so-called scientific method consists of.
c) The critical text conceptions of scientific knowledge, which has been conceived as a result of a method
d) The text argues in favor of the plurality of methods available for each science to achieve its truths

Explanation:

clearcutting reproduces a new even-aged stand by completely removing the mature stand.

clearcutting as a silvicultural treatment has several characteristics:

it causes a sudden environmental change

it removes the seed source from the regeneration area

the configuration of the clearcut may affect seed dispersal

it begins a new rotation

it will eliminate some pests that require forest cover

overall, it temporarily removes the forest cover, transforming the forest community and environment.

clearcutting followed by artificial (seeded or planted) regeneration has several advantages:

we can avoid delay in restocking the site

we can introduce a selected species, seed source, and genotype

we can control arrangement and spacing

we can achieve uniformity in the new stand

we can overcome the problems associated with securing sufficient natural regeneration.

the shelterwood method involves the removal of most of the mature stand at the end of the rotation, but a portion of the mature stand is left standing.   the shelterwood method serves three basic purposes:

to prepare the stand for production of abundant seed

to modify the environment in a way that promotes germination and survival of the selected species

to build up the amount and size of advance regeneration to ensure the prompt restocking of the new stand following overstory removal.

the shelterwood method involves a sequence of 3 cuttings:

preparatory cuttings: make the seed trees more vigorous and set the stage for regeneration. see our thinning page for more information.

establishment/seed cuttings: open up enough vacant growing space to allow establishment of the new regeneration.

removal cuttings: uncover the new crop to allow it to fill the growing space.

the residual trees in the shelterwood must:

be sturdy and windfirm

be able to survive exposure

flower and reproduce seed

be the best trees of the mature stand

keep in mind that the shelter trees must not occupy the entire site.   a void must be created in order to make room for the new regeneration. the amount of shelter to leave will depend on the following factors:

species characteristics (seeding and shelter requirements)

the number of cuttings in the cutting sequence (1, 2, or 3)

landowner objectives

the size of the area to be regenerated

the final removal harvest level required to be profitable

the shelter must be removed before it impedes the growth of the new stand or threatens its survival.
