Choose the incorrect one from the underlined words in the following sentence. In addition, the Hall-Petch relationship breaks down in metal alloys when grain size is reduced below a critical value, where the strength and hardness decrease with grain sizes. This is due to the activation of dislocations requires a higher stress than that of other deformation mechanisms such as GB sliding, GB diffusion, and GB rotation.

Choose the incorrect one from the underlined words in the following sentence. The recent observation of the reverse Hall-Petch relation in nanocrystalline ceramics offers a possible pathway to achieve enhanced ductility for traditional brittle ceramics via the nanosize effect, just as nanocrystalline metals and alloys. In addition, the underlying deformation mechanisms of nanocrystalline ceramics have not been well established.
Choose the incorrect one from the underlined words in the following sentence.This time when it is taken is cumulative: it includes time taken for any failed attempts, until the point when a successful login occurs.

Tick the type of the citation system in the text.People consistently choose “weak” passwords [7] for many reasons, including users trying to manage on average 25 password-protected accounts [8]. Losing strategies include blaming users, and imposing complex password rules. Some claim that choosing weak passwords (despite repeated advice otherwise) is a rational economic response [12]. Biddle et al., 2011:970.
