Explanation

Since the last part of the sentence mentions the problem of disposing of old equipment, it is likely that the three-year-old personal computer described by Blank
(ii) will be characterized by a word that suggests why it is being disposed of. Neither “familiar” nor “inestimable” suggests something that needs to be cast off, while “outdated” does; therefore, it is the correct response. Since the outdated three-year- old computer is presented as an example of the trend in technology mentioned in the first part of the sentence, Blank (i) must be completed with a word that characterizes this outdatedness. “Obsolescence” does exactly that, so it is the correct response. Neither “affordability” nor “complexity” is exemplified by computers that become quickly outdated, so they are incorrect. Thus the correct answer is obsolescence (Choice C) and outdated (Choice D).

No.

Simply because the on-going of the question is in the same direction. Considering that the second blank is outdated (computer related) the first one must be the obsolescence and not complexity.

Hope this helps
