Cold  air  is  associated  with    viral  infection  because  you've  essentially  lost  half  of  your  immunity  just  by  that  small  drop  in  temperature,  said  rhinologist  Dr.  Benjamin  Bleier.  A  respiratory  virus  or  bacteria    the  nose,  the  main  point  of  entry  into  the  body.  Immediately,  the  front  of  the  nose  detects  the  germ,  well  before  the  back  of  the  nose  is  aware  of  the  intruder,  the  team  discovered.  At  that  point,  cells  lining  the  nose  immediately  begin  creating  billions  of  simple  copies  of  themselves  called  extracellular  vesicles,  or  EV'.  EV's  can't  divide  like  cells  can,  but  they  are  like  little  mini  versions  of  cells    designed  to  go  and  kill  these  viruses,  Bleier  said.  What  we  found  is  that  when  you're  exposed  to  cold  air,  the  temperature  in  your  nose  can  drop  by  as  much  as  9  degrees  Fahrenheit.  And  that's  enough  to  essentially    all  three  of  those  immune  advantages  that  the  nose  has,  Bleier  said.

Correct answer: increased

Explanation: The word 'increased' fits grammatically as it describes a rise in the likelihood of viral infection due to cold air. The context indicates that cold air leads to a higher risk, aligning with the overall sentiment of the sentence.

Meaning: 'Increased' means to become greater in amount, number, or degree, indicating that cold air raises the chances of viral infections.

Wrong options:

  • decreased: 'Decreased' implies a reduction, which contradicts the context that cold air raises infection risk.
  • stable: 'Stable' suggests no change, which does not align with the idea that cold air affects immunity and infection rates.
  • overrated: 'Overrated' means given too much importance, which is irrelevant in this context as it does not relate to the increase in viral infections.
Correct answer: invades

Explanation: The verb 'invades' is appropriate as it describes how a virus or bacteria enters the body through the nose. This aligns with the context of the sentence, which discusses the entry point for infections.

Meaning: 'Invades' means to enter forcefully or in large numbers, particularly in a harmful way, which accurately describes the action of viruses or bacteria entering the body.

Wrong options:

  • hurts: 'Hurts' implies causing pain, which does not accurately describe the action of a virus entering the body.
  • intervenes: 'Intervenes' suggests coming between or interfering, which is not the correct action for how viruses operate in this context.
  • protects: 'Protects' means to keep safe from harm, which is the opposite of what a virus does.
Correct answer: specifically

Explanation: The adverb 'specifically' fits well as it indicates that the EVs are designed for a particular purpose, which is to target viruses. This aligns with the context of the sentence that describes their function.

Meaning: 'Specifically' means in a detailed and exact manner, indicating that the EVs have a targeted role in combating viruses.

Wrong options:

  • suddenly: 'Suddenly' implies an unexpected occurrence, which does not relate to the designed function of EVs.
  • responsibly: 'Responsibly' suggests acting with accountability, which is not relevant to the context of how EVs operate.
  • obtrusively: 'Obtrusively' means in a way that is noticeable or intrusive, which does not accurately describe the intended function of EVs.
Correct answer: knock out

Explanation: The phrase 'knock out' is suitable as it conveys the idea of eliminating or rendering ineffective the immune advantages. This fits contextually with the discussion of how cold air impacts immunity.

Meaning: 'Knock out' means to eliminate or incapacitate, indicating that exposure to cold air can remove the immune benefits of the nose.

Wrong options:

  • work out: 'Work out' typically means to exercise or solve a problem, which does not fit the context of immune function.
  • find out: 'Find out' means to discover information, which is unrelated to the action of affecting immune advantages.
  • set out: 'Set out' means to begin a journey or to aim to achieve something, which does not apply to the context of immune response.
