                      1.  Why is it difficult for Krishnan to explain               (a)  It is thicker at the poles and thinner
                         “cold” to Amir without measurement?
                                                                                       at the equator.
                                (a)  Because temperature does not                   (b)  It is thicker in tropical regions and
                                   change.                                             thinner at the poles.
                                (b)  Because cold is felt differently by            (c)  It has equal thickness everywhere.

                                                                                    (d)  It exists only above oceans.
                                (c)  Because weather cannot be
                                   measured.                              5.  What pattern can be observed in how rainfall
                                (d)  Because only scientists can feel        is measured using the instrument shown?
                                   temperature.

                      2.  Which logical conclusion explains why digital
                         thermometers are preferred?

                                (a)  They are cheaper only.

                                (b)  They are less accurate.

                                (c)  They are more precise and can
                                   record more data.

                                (d)  They do not measure temperature.
                      3.  Why is weather mainly experienced in the                  (a)  Rainwater directly disappears
                         troposphere?                                                  after falling.
                                                                                    (b)  Rainwater is collected in a
                                (a)  It contains no air.
                                                                                       container and measured as depth
                                (b)  It is the outermost layer.                        using a scale.
                                                                                    (c)  Rainwater changes temperature
                                (c)  It contains most air and supports
                                                                                       and is measured accordingly.

                                (d)  It is the coldest layer.                          collection process.
