Question

millions of americans replace their cell phones every couple of years, and many of the old phones get tossed into the trash. this creates a dangerous and avoidable problem. the phones go directly to landfills or trash - processing plants, where their lithium batteries can explode and start fires. in addition, a variety of toxic chemicals can seep out, contaminating soil and water.
donating used phones to charity is a wise solution. some charitable organizations dismantle phones and sell the parts; others overhaul phones and give them to people in need. the charities that accept phones range from local church groups to international anti - poverty organizations. wireless companies may also take back phones for recycling—a better choice than trashing them—but the phones may not go to a good cause. join me and donate your phone for good!
which best shows that the author’s purpose is to convince readers of the benefits of donating used cell phones?
the author provides standards for judging which charities (church groups or anti - poverty organizations) should get phones.
the author warns against giving used phones back to phone companies.
the author provides reasons and evidence to support the argument that donating used phones to charity is a wise solution.

Explanation:

The author presents the problem of discarded cell - phones (lithium battery explosions, toxic chemical seepage) and then offers donating to charity as a solution. By providing reasons (charities dismantle/sell parts, overhaul and give to those in need) and evidence (types of charities that accept phones), the author builds an argument for the benefits of donating. The first option about standards for charities is not the main focus of convincing about donation benefits. The second option about warning against phone companies is just a side - note and not the core of convincing about donation.

Answer:

The author provides reasons and evidence to support the argument that Donating used phones to charity is a wise solution.
