Question 8 
 The James Webb telescope, recently launched in space, is giving humankind unprecedented access to 
the depths of time by imaging very old stars formed almost 13 billion years ago. Astrophysicists and 
cosmologists believe that this odyssey in space may even shed light on the existence of dark matter. 
Dark matter is supposed to interact only via the gravitational interaction and not through the 
electromagnetic-, the weak- or the strong-interaction. This may justify the epithet “dark” in dark matter.  
 Based on the above paragraph, which one of the following statements is FALSE?  
 (A) No other telescope has captured images of stars older than those captured by the James Webb  
 telescope.  
  (B) People other than astrophysicists and cosmologists may also believe in the existence of dark  
 matter. 
 (C) The James Webb telescope could be of use in the research on dark matter. 
 (D) If dark matter was known to interact via the strong-interaction, then the epithet “dark” would  
 be justified.
