A sniper planning to assassinate a target must be sure that the right person is in the cross-hairs before pulling the trigger. Forces commonly use software that compares a suspect’s facial features or pace with those in records of biometric data. Such technology can, however, be hindered by a disguise and hence a new tool, which can measure, from up to 200 metres away, the minute vibrations induced in clothing by someone’s heartbeat, is being introduced. Since hearts differ in both shape and contraction pattern, the details of heartbeats vary from person to person. Thus, using this tool, an assassin will be able to eliminate the cases of mistaken identity.

Which of the following can be inferred if the information above is presumed accurate?

(A) Significant research is going on to improve the accuracy of snipers.

(B) The targets often escape the sniper by changing their appearance.

(C) World’s best makeup will also not be able to save a target from sniper once the new tool starts getting used.

(D) The new tool is an improved version of the commonly used software.

(E) The minute vibrations induced in clothing by a person’s heartbeat cannot be manipulated
