     Directions: Each passage in this group is followed by questions based on its content.

     After reading a passage, choose the best answer to each question. Answer

    all questions

     following a passage on the basis of what is stated or implied in that passage.

     lt has been known for many decades that the appear-

     ance of sunspots is roughly periodic, with an average

     cycle of eleven years. Moreover, the incidence of solar

     flares and the flux of solar cosmic rays, ultraviolet radia-

    网址?www.kaogo.com E-mail?master@kaogo.com

     tion, and x-radiation all vary directly with the sunspot (5)

     cycle. But after more than a century of investigation. the

     relation of these and other phenomena, known collec-

     tively as the solar-activity cycle, to terrescrial weather

     and climate remains unclear. For example. the sunspot

     cycle and the allied rnagnetic-polarity cycle have been (10)

     linked to periodicities discerned in records of such vari-

     ables as rainhll. temperature, and winds. lnvariably,

     however, the relation is weak. and commonly ofdubious

     statistical significance.

     Effects of solar variability over longer terms have also (15)

     been sought. The absence of recorded sunspot activity in

     the notes kept by European observers in the late seven-

     teenth and early eighteenth centuries has led some schol-

     ars to postulate a brief cessation of sunspot activity at

     that time (a period called the Maunder minimum). The (20)

     Maunder minimum has been linked to a span of unusual

     cold in Europe extending from the sixteenth to the early

     nineteenth centuries. The reality of the Maunder mini-

     mum has yet to be established, however, especially since

     the records that Chinese naked-eye observers of solar (25)

     activity made at that time appear to contradict it. Scien-

     tists have also sought evidence of long-term solar period-

    网址?www.kaogo.com E-mail?master@kaogo.com

     icities by examining indirect climatological data, such as

     fossil recoras of the thickness of ancient tree rings. These

     studies, however, failed to link unequivocally terrestrial(30)

     climate and the solar-activity cycle, or even to contirm

     the cycle's past existenue.

     If consistPn! and re!iab!e geo!sgigal~-arek-xologieal

     evidence tracing the solar-activity cycle in the distant

     past could be found, it might also resolve an important(35)

     issue in solar physics: how to model solar activity. Cur-

     rently, chere are two models of solar activity. The tirst

     supposes that the Sun's internal motions (caused by

     rotation and convection) interact with its large-scale

     magnetic field to produce a dynamo. a device in which(40)

     mechanical energy is converted into the energy of a mag-

     netic field. ln short. the Sun's large-scale magnetic field

     is taken to be self-sustaining, so that the solar-activity

     cycle it drives would be maintained with little overall

     changc for perhaps billions of years. The alternative(45)

     exp)anarion supposes that the Sun's large-sca)e magnetic

     field is a remnant of the field the Sun acquired when it

     formed, and is not sustained against decay. In this

     model. the solar mechanism dependent on the Sun's

     magnetiC field runs down more quickly. Thus, the char-(50)

    网址?www.kaogo.com E-mail?master@kaogo.com

     acteristics of the solar-activity cycle uvuld be expected to

     change over a long period of time. Modern solar obser-

     vations span too short a time to reveal whether present

     cyclical solar aCtivity is a long-lived feature of the Sun,

     or merely a transient phenomenon.

     17. The author focuses primarily on

     (A) presenting two competing scientific theories concerning solar

     activity and evaluating geological evidence often cited to support them

     (B) giving a brief overview of some recent scientifrc developments

     in s'olar physics and assessing their impact on future climatological research

     (C) discussing the difficulties involved in linkinl: ter- restrial

     phenomena with solar activity and indicating how resolving that issue

     could have an impact on our understanding of solar physics

     (D) pointing out the futility of a certain line of sci- entific inquiry

     into the terrestrial effects of solar activity and recommendine ita

     aban- donment in favor of purely physics-oriented research

     (E) outlinine the specific reasons why a problem in solar physics has

     not yet been solved and faulting the overly theoretical approach of modern

     physicists.

     18. Which of th.e following statements about the two models of solar

     activity. as they are described in lines 37-55, is accurate?

    网址?www.kaogo.com E-mail?master@kaogo.com

     (A) In both modgls cyclical solar activity is regarded as a long-lived

     feature of the Sun, persisting with little change over billions of years.

     (B) Tn both models the solar-activity cycle is hypothesized as being

     dependent on the large-scale solar magnetic field.

     (C) Tn one model the Sun's magnetic fieid is thought to play a role in

     causing solar activ- ity, whereas in the other model it is not.

     (D) In one model solar activity is presumed to be unrelated to terrestrial

     phenomena. whereas in the other model solar activity is thought to have

     observable effects on the Earth.

     (E) In one model cycles of solar activity with peri- odicities longer than

     a few decades are con- sidered to be impossible, whereas in the other model

     such cycles are predicted.

     19. According to the passage, late seventeenth- and early eighteenth-century

     Chinese records are impor- tant for which of the following reasons?

     (A) They suggest that the data on which the Maunder minimum was predicated

     were incorrect.

     (B) They syggest that the Maunder minimum can- not be related to climate.

     (C) Thcy suggest that the Maunder minimum might be \-'alid only for Europe.

     (D) They establish the existence of a span of unusu- ally cold weather

     worldwide at the time of the Maunder minimum.
